Abstract ：
The water oxidation is a promising method for generating the renewable energy. However, the high catalytic performance using stable electrocatalysts in alkali solutions remains limited. In this work, we herein report a facile method of deposition of NiAl-LDH electrocatalyst that addresses the above challenge under a magnetic field. Water oxidation behavior of the new electrodeposited nickel-aluminum layered double hydroxides (NiAlLDH) on Ni electroplated on the Cu substrate and their remarkable improvements in electrocatalytic activity under the external magnetic fields in alkali solutions were studied. Ni films were first electroplated on the Cu substrate using the direct current (DC) method. NiAl-LDH was coated on the Ni/Cu substrates using the electrochemical deposition method, and their water oxidation performance was investigated in the KOH aqueous solution (0.1 mol center dot L-1) at 25 degrees C in the absence and presence of magnetic field. It was found that the oxygen evolution reaction (OER) over NiAl-LDH/Ni/Cu was improved when water oxidation was conducted under a magnetic field (mu oH perpendicular to = 0.2 T) by decreasing the onset potential, Tafel slope, and overpotential or by increasing the current density (about 54 mA center dot cm- 2). The effects were even more pronounced when the magnetic field was applied perpendicular to the electrode plane, reaching the OER overpotential of about 310 mV and the Tafel slop of about 142 mV center dot dec- 1. We interpreted the effect of magnetic water electrolysis by the ordinary magnetohydrodynamics (MHD) which enhanced the mass transport, increased the limiting current density, and removed the blocking oxygen gas bubbles accumulated on the electrode surface. The present investigation provides a low-cost electrocatalyst system for efficient electrochemical water oxidation.

Abstract ：
The Bi3O4Br nanosheets and xBi2WO6-Bi3O4Br (Bi2WO6/Bi3O4Br molar ratio (x) = 0.03, 0.08, and 0.15) heterostructures were prepared using the hydrothermal and ion-exchange strategies, respectively. Due to the strong interface interaction and staggered energy band structure between Bi2WO6 and Bi3O4Br, a Z-scheme charge migration path was established, which improved the charge separation and migration efficiencies and retained enough redox potentials of the charge carriers. The bisphenol A (BPA) degradation activities over the xBi2- WO6-Bi3O4Br photocatalysts under visible-light illumination were much higher than those over their single components. The 0.08Bi2WO6-Bi3O4Br photocatalyst exhibited the highest photocatalytic performance, which was 2.53 and 7.11 times higher than those over the Bi3O4Br and Bi2WO6 photocatalysts, respectively. Furthermore, we also investigated the effects of ions, pH, and water kinds on photocatalytic activity of the typical sample, and proposed the possible photocatalytic degradation mechanism. This work provides a useful guideline for constructing high-efficiency photocatalysts for wastewater treatments and expanding photocatalytic applications of the two-dimensional Bi-based semiconductors.

Abstract ：
The Pt/CeO2 catalyst has attracted significant attention due to its exceptional performance in NO oxidation. This study comprehensively examines the effects of calcination temperature and H-2 pretreatment on the structure and activity of the Pt/CeO2 catalyst. Experimental findings indicate that the calcination temperature significantly affects the catalyst's redox performance, thereby modulating its efficacy in NO oxidation reactions. H-2 pretreatment facilitates the creation of oxygen vacancies on the catalyst, assisted by the reduction in PtOx to Pt, enhancing the formation of activated oxygen and thereby improving NO oxidation. This study offers valuable insights into the design and optimization of Pt/CeO2 catalysts for environmental applications, particularly in the development of exhaust gas after-treatment technologies.

Abstract ：
To improve catalytic activity and sulfur dioxide and water resistance of the 0.25Pt/TiO2 catalyst and explore the simple catalyst preparation method suitable for industrial production, we developed a 0.25Pt-CoOx/TiO2 catalyst in the present work. The 0.25Pt-CoOx/TiO2 catalyst was prepared via the impregnation-, precipitation-, and ball milling-combined method, and its catalytic CO oxidation performance as well as sulfur dioxide and water resistance was examined. It was shown that the 0.25Pt-CoOx/TiO2 catalyst exhibited a good catalytic activity and good resistance to sulfur dioxide and water. The T50, T90, and T100 (the temperatures for achieving CO conversions of 50, 90, and 100%) over the 0.25Pt-CoOx/TiO2 catalyst at a space velocity of 47,872 mL/(g h) were 95, 110, and 120 degrees C, which were 70, 57, and 50 degrees C lower than those over the 0.25Pt/TiO2 catalyst, respectively. Meanwhile, CO conversions over 0.25Pt-CoOx/TiO2 were maintained at above 99% within 12 h of reaction in the co-presence of SO2 and H2O. The doping of CoOx to 0.25Pt/TiO2 increased the surface Co3+ species concentration, redox ability, and acid site number of the 0.25Pt-CoOx/TiO2 catalyst, which favored the enhancements in catalytic activity and SO2- and H2O-resistant performance. In addition, it was also found that an appropriate amount of H2O introduction to the reaction system could promote the oxidation of CO and inhibit the negative effect of SO2 addition on CO oxidation over 0.25Pt-CoOx/TiO2, thus making this catalyst show good CO oxidation activity and good sulfur dioxide and water resistance. We are sure that the developed 0.25Pt-CoOx/ TiO2 catalyst has a great application potential in the removal of the flue gas emissions from the iron and steel industries.

Abstract ：
Among the developed electrocatalysts, NiCr-layered double hydroxides (NiCr-LDH) are one of the most effective electrocatalytic materials for water oxidation. However, applications of such a kind of materials are practically limited due to their poor electric conductivity. In this work, the single-walled carbon nanotube (SWCNT) was doped to NiCr-LDH, and the LDH-based nanocomposites were synthesized using the one-step ultrasonic-assisted method. Physicochemical properties of the NiCr-LDH/SWCNT composites were characterized by means of X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), energy dispersive X-ray (EDX) analysis, transmission electron microscopy (TEM), field emission-scanning electron microscopy (FE-SEM), and linear sweep voltammetry (LSV). The NiCr-LDH/SWCNT composites were used as effective nanomaterials for oxygen evolution reaction (OER) at a near neutral medium. The LSV results confirm that the overpotential of the NiCr-LDH/SWCNT-0.006 sample decreased to about 120 mV at pH = 9.5, as compared with that of the NiCr-LDH or NiCr-LDH-SWCNT-0.006 (prepared by the two-step method) sample. The high oxygen evolution activity of NiCr-LDH/SWCNT-0.006 was associated with the co-presence of the homogeneously dispersed NiCr-LDH, good electrochemical activity, and high electrical conductivity. In addition, the as-prepared optimized NiCr-LDH/SWCNT electrocatalyst was highly stable for the OER reaction. (c) 2022 Hydrogen Energy Publications LLC. Published by Elsevier Ltd.

Abstract ：
Industrial flue gas has a great impact on the atmosphere environment and human health, and its emission temperatures are usually below 180 degrees C, which needs a new technology that can catalyze the removal of the multicomponent VOCs over high-performance catalysts in the presence of ozone. In this work, we prepared the Pt/CeO2 catalysts with different morphologies of Pt particles and investigated their catalytic performance for the ozonization of mixed VOCs (i.e., toluene and chlorobenzene (CB)). Among all of the as-prepared samples, Pt NRs/CeO2 with nanorod-like Pt particles showed excellent catalytic performance for the ozonization of toluene and CB. The T-50% (the temperature at VOC conversion = 50%) values for toluene and CB ozonization were 40 and 48 degrees C at a space velocity of 40,000 mL g(-1) h(-1), respectively. The results of characterization revealed that the reactive oxygen species involved in the VOC ozonization were mainly the O-2(-) and O-2(2-) species, surface oxygen vacancies of CeO2 were the active sites for the conversion of ozone to the reactive oxygen species, and the O-2(-) species was the mainly active oxygen species in the low-temperature VOC oxidation. Furthermore, partial reactive oxygen species reacted with the Ptn+ species to generate more amount of the Pt-0 species, and the metallic platinum species was the main active site for the adsorption and activation of toluene and CB. The chemisorbed VOCs at the Pt-0 sites reacted with the reactive oxygen species at the interface of Pt and CeO2, resulting in the excellent low-temperature catalytic activity. Compared with the reaction without ozone participation, we find that the participation of ozone can not only decrease the reaction temperature but also reduce the production of toxic byproducts. We are sure that the Pt/CeO2 catalyst is promising in practical application for elimination of the VOCs from industrial flue gas.

Abstract ：
Pt-based commercial catalysts tend to be poisoned by chlorine species in the oxidation of chlorinated volatile organic compounds (CVOCs), which greatly limits their wide applications. It is vital to develop the active catalysts with good chlorine resistance. In the present work, the novel supported ternary metallic catalysts (PtSnM/ CeO2; M = Mn, W, Nb) with the closely coupled multi-active sites show good catalytic performance and excellent chlorine resistance for the oxidation of toluene and chlorobenzene (CB), and can effectively inhibit formation of the toxic chlorine-containing by-products. The catalytic activity for toluene oxidation in the mixed VOCs system follows the sequence: PtSnMn/CeO2 > PtSnW/CeO2 & AP;PtSnNb/CeO2 > PtSn/CeO2 > Pt/CeO2. The change of the electron structure around Pt results in the difference in adsorption capacity of toluene and CB. The C-Cl bond is first dissociated at the Bronsted acid sites, and the non-chlorinated organic compounds are oxidized at the Pt sites that contact with the acid sites in the proximity. Additional water provides sufficient protons to react with Cl species, enhancing the desorption amount of HCl; furthermore, the water also reacts with the adsorbed oxygen to generate new oxygen species, which participates in the oxidation of VOCs, so as to accelerate the removal of Cl species on the catalyst surface and reduce the more toxic polychlorine by-products. This work is helpful for developing the supported noble metal catalysts with good chlorine-resistant performance in the oxidation of multicomponent VOCs under the actual industrial conditions.

Abstract ：
As typical air pollutants, CO, CH4, and volatile organic compounds (VOCs) have received great attention due to their negative impact on the environment and human health. Heterogeneous catalysts are widely used in the catalytic removal of exhaust emission from industrial and automobile sources but still suffer from deactivation because of various factors. The development of a catalyst with excellent catalytic stability is highly desired. We herein summarized the recent progress for enhancing the catalytic stability of catalysts and tried to obtain an in-depth understanding of the long-term durability, resistance to sinter, and tolerance for multi-impurities. Finally, the current challenges and future perspectives for developing stable and highly efficient catalysts in the fields of synergistic catalytic removal of pollutants or resource utilization of VOCs via the selective catalytic oxidation are proposed.

Abstract ：
The painting and electronics industries simultaneously release aromatic compounds and chlorinated organics. The development of catalysts with synergistic control of these pollutants is of great significance to achieve air purification. However, developing active catalysts while maintaining good chlorine resistance remain a huge challenge due to the difficulty of the trade-off between the redox properties and acidity and the production of polychlorinated byproducts. Herein, we introduce a novel tandem PtSn/CeO2 & Mn/ZSM-5 catalyst and investigate its catalytic performance for multicomponent volatile organic compounds (VOCs) oxidation. The two individual catalysts, PtSn/CeO2 and Mn/ZSM-5, were used to catalyze two distinct sequential reactions. PtSn/CeO2 catalyzed toluene oxidation to produce CO2 and H2O. Meanwhile, the introduction of SnOx favored the adsorption of trichloroethylene (TCE) molecules that prevented Pt sites from chlorine poisoning and possibly converted adsorbed TCE into intermediates, which were subsequently oxidized deeply by the nearby Mn/ZSM-5. This approach resulted in a remarkable oxidation efficiency for toluene (T90 = 296 degrees C) and TCE (T90 = 384 degrees C), with fewer unexpected toxic byproducts (chlorobenzene and 4-chlorotoluene). Furthermore, the tandem catalyst possessed excellent chlorine and water resistances. In conclusion, the above findings provide new insights into the design and/or syntheses of advanced catalysts for widespread VOCs pollution control.
