Abstract ：
In this work, a series of M/TiO2 (M= Cu, Mn, Co, Ni) nanofiber catalysts were prepared by electrospinning technology, and their photothermal synergism on toluene oxidation was investigated. The sequence in catalytic activity for the oxidation of toluene was Cu/TiO2 > Mn/TiO2 > TiO2 > Co/TiO2 > Ni/TiO2. The excellent catalytic performance of Cu/TiO2 came from its good low-temperature reducibility and lattice oxygen mobility. The activation ability of photo-generated carriers for O-2 and lattice oxygen is the reason why Cu/TiO2 have the best promotional effect of light irradiation. In situ DRIFTS revealed the reaction pathway of photothermal catalytic oxidation of toluene on Cu/TiO2: Toluene and O-2 first reacted with holes and electrons to generate benzyl radicals and center dot O-2(-). These benzyl radicals and superoxide radicals then couple with protons to form hydro-peroxide intermediates. The hydro-peroxide intermediates undergone dehydration to form benzaldehyde, which was further oxidized by O- ions to yield benzoic acid. Finally, benzoic acid was completely oxidized to CO2 and H2O. In this process, the adsorbed oxygen promoted the generation of benzaldehyde, while lattice oxygen mainly promoted the further decomposition of benzaldehyde.

Abstract ：
The dissociation of water is essential to water gas shift (WGS) reaction, and the presence of oxygen vacancies can facilitate this key step. Herein, a series of perovskite supported Pd single atoms catalysts were prepared via deposition precipitation method. The incorporation of Pd single atoms can effectively promote the formation of oxygen vacancy on the surface of the catalyst, improving the low temperature reducibility, the ratio of Mn4+ / Mn3+ and O-ads/O-lat compared with support. Among all samples, 0.82 Pd/La0.5Ca0.5MnO3/SBA-15 with the most oxygen vacancies presented 83.6 % CO conversion at 400 degrees C, specific reaction rate (0.54 mol(CO) g(Pd)(-1) h(-1) ), and TOF (3.77.10(-2) s(-1)). DFT calculation proved that Pd doping can effectively decreased energy barrier of H2O dissociation, and promoted the formation of oxygen vacancies. This work provides experimental and theoretical insights into the rational design of highly active perovskite supported Pd single atom catalysts for WGS reaction.

Abstract ：
Photocatalytic CO2 reduction technology plays a significant role in the energy and environmental sectors, highlighting the necessity for developing high-efficiency and stable catalysts. In this study, a novel photocatalyst, x NiCo 2 O 4 /CN (x = 1, 3, and 5 wt%), was synthesized by depositing zeolitic imidazolate framework-67 (ZIF-67)derived nickel cobaltate (NiCo2O4) hollow nanocages onto porous graphitic carbon nitride (g-C3N4, CN) nano sheets for photocatalytic CO2 reduction. Under visible light irradiation, the resulting 3NiCo2O4/CN photocatalyst demonstrated exceptional CO yields of up to 2879.5 mu mol g- 1 h- 1 , surpassing those of NiCo2O4 and CN alone by factors of 3.3 and 11.6, respectively. The introduction of hollow NiCo2O4 nanocages increased the specific surface area of the material and enhanced the number of active sites, while strengthening visible light absorption. The creation of a built-in electric field, induced by the Fermi level difference between the two materials, was confirmed through ultraviolet photoelectron spectroscopy (UPS) characterization. This resulted in the formation of a Z-scheme heterojunction, significantly enhancing the separation and migration of photogenerated charge carriers. Notably, 3NiCo2O4/CN exhibits excellent stability during long-term photocatalytic reactions, ensuring reliable performance for practical applications. This study offers novel insights and methodologies for developing efficient photocatalytic CO2 reduction catalysts.

Abstract ：
Graphitic carbon nitride (g-C3N4), because of its appropriate band gap, is a prospective option for photocatalytic CO2 reduction. Nevertheless, the rapid recombination of photogenerated charge carriers restricts the photocatalytic efficiency of CN. In this study, a one-step chemical reaction followed by low-temperature calcination method was innovatively used to anchor zero-dimensional (0D) Ni-Fe bimetallic oxide quantum dots (NFO QDs) onto the surface of two-dimensional (2D) porous CN nanosheets. Under visible light irradiation, a CO yield of 1571.55 mu mol g- 1 h- 1 was achieved by the composite catalyst (NFO QDs/CN). Ultraviolet photoelectron spectroscopy (UPS) and in situ X-ray photoelectron spectroscopy (XPS) confirmed the existence of an in-built electric field at the interface between NFO QDs and CN, which performed as a Z-scheme heterojunction. Photoluminescence spectroscopy (PL), electrochemical impedance spectroscopy (EIS), and UV-visible diffuse reflectance spectroscopy (UV-Vis DRS) all showed that improved spatial separation of photogenerated electron-hole pairs and increased light absorption were responsible for the improved photocatalytic performance. Moreover, morphological characterization revealed that CN possessed a lamellar porous structure, coupled with the small size of the NFO QDs, which resulted in an increased specific surface area. This study offers fresh perspectives on the design of high-performance CN-based composite photocatalysts for energy production.

Abstract ：
As a novel medium-temperature CO(2 )adsorbent, K+ doped and graphitic carbon nitride modified layered double oxide composite (xK/CN-LDO, x = 15, 20, and 25 wt%) were prepared via in-situ synthesis and impregnation methods. Their adsorption performance was evaluated by thermal gravimetric analyzer. g-C3N4-modified LDO (CN-LDO) exhibited a CO2 adsorption capacity of 0.46 mmol/g, 1.39 times higher than the 0.33 mmol/g observed for LDO. This enhancement was attributed to the increased specific surface area and the exposure of additional extractable sites. Further doping with K significantly enhanced the adsorption uptake of xK/CN-LDO. Notably, 20 K/CN-LDO achieved the highest CO2 adsorption uptake of 0.82 mmol/g, representing a 2.48-fold increase compared to LDO. This further enhancement can be ascribed to K's ability to alter the distribution of chemical adsorption sites, thereby providing an optimal number of basic sites. In-situ DRIFTS analysis revealed that CO(2 )predominantly existed in the form of carbonate species, while adsorption kinetics studies show that the dominant mechanism is chemical adsorption, with external diffusion being the primary adsorption process. Furthermore, 20 K/CN-LDO exhibited significantly higher regeneration efficiency of 72.4 % after 10 cycles, showcasing its promising practical prospects for application in the SEWGS process.

Abstract ：
Lead (Pb) is a heavy metal commonly found in industrial exhaust gases, which can reduce catalytic activity of a catalyst for the NH3-SCR reaction. In this study, 4.0 wt% Mn-loaded Fe-pillared interlayer clay (4Mn/Fe-PILC) and its Co-modified catalyst (2Co-4Mn/Fe-PILC) were prepared, in the meanwhile the 4Mn/Fe-PILC-Pb and 2Co-4Mn/Fe-PILC-Pb samples were also obtained using the impregnation method with a Pb(CH3COO)(2) aqueous solution. It was found that the addition of 2.0 wt% cobalt could significantly enhance Pb resistance of the 4Mn/Fe-PILC catalyst. The characterization results revealed that the doping of Co to Mn/Fe-PILC increased the surface Mn4+ species concentration, reducibility, and acid site amount, thereby improving Pb resistance of the catalyst. Furthermore, the in situ DRIFTS results demonstrated that Co modification enhanced the adsorption capacity of NH3 or NO, especially influenced formation of the NH3 intermediates and bridging nitrate species, which were also conducive to the improvement in Pb resistance of the catalyst.

Abstract ：
A series of RE-3Cu/Zr-PILC (RE = La, Ce, Nd, Eu) catalysts were prepared via an impregnation method and activities for NH3-SCR were evaluated. The physicochemical properties of each catalyst were explored using XRD, BET, H-2-TPR, NH3-TPD, XPS and in-situ DRIFTS techniques. The doping of RE had enhanced the NH3-SCR efficiency of 3Cu/Zr-PILC. Among them, the 6Ce-3Cu/Zr-PILC sample demonstrated exceptional performance, achieving NO conversion rates exceeding 90% within the temperature range of 250-350 degrees C. Moreover, it reached its peak NO conversion rate of 96.3% at 300 degrees C while maintaining an impressive resistance to SO2. According to the results of TPR, TPD and XPS analysis, the modification of RE (especially Ce) enhanced the redox properties, the surface acidity, the atomic ratio of Cu2+/Cu+ and the amount of surface chemisorbed oxygen in the 3Cu/Zr-PILC samples, all of these are favorable for the NH3-SCR reaction. Furthermore, in-situ DRIFTS analysis reveals that the NH3-SCR reaction of RE-3Cu/Zr-PILC samples at low temperatures is governed by the Langmuir-Hinshelwood (L-H) and Eley-Rideal (E-R) mechanisms, with the L-H mechanism being the predominant factor.

Abstract ：
The xCN/Ce-OMS-2 (x is the nominal weight percentages of g-C3N4, x = 5.0, 10.0, and 15.0 wt%) catalysts were prepared via an in-situ synthesis method. Physicochemical properties of the as-prepared materials were measured by means of the XRD, TEM, SEM, BET, XPS, H2-TPR, NH3-TPD, and in-situ DRIFTS techniques, and their catalytic activities for the selective catalytic reduction of NOx with NH3 (NH3-SCR) at low temperatures were evaluated. Among all the catalysts, the 10CN/Ce-OMS-2 catalyst showed the widest temperature span for NH3-SCR reaction and the best resistance to SO2 poisoning. This may result from that the modification of g-C3N4 promoted the electron transfer in catalyst, not only increased the concentration of active Mn4+ species and chemisorbed oxygen species, but also improved the surface acidity of the catalyst. In-situ DRIFTS results further showed that the modification of g-C3N4 increased the amount of acid sites and enhanced the formation of NH3 or NO intermediates (i.e., monodentate and bidentate nitrate), which enhanced the reaction activity of the catalyst.

Abstract ：
The Ni-loaded cryptomelane-type manganese oxide octahedral molecular sieve (OMS-2) catalysts (xNi/OMS-2: x = 1, 3, 5, and 10 wt%) were prepared by a pre-incorporation method. Physicochemical properties of the as-synthesized materials were characterized by means of various techniques, and their catalytic activities for CO, ethyl acetate, and toluene oxidation were evaluated.The loading of Ni played an important role in improving physicochemical propertiesof OMS-2. Among all of the samples, 5Ni/OMS-2 exhibited the best catalytic activity, with the T-90 being 155 degrees C for CO oxidation at a space velocity (SV) of 60,000 mL/(g center dot h), 225 degrees C for ethyl acetate oxidation at an SV of 240,000 mL/(g center dot h), and 300 degrees C for toluene oxidation at an SV of 240,000 mL/(g center dot h), which was due to its high Mn3+ content and O-ads concentration, good low-temperature reducibility and lattice oxygen mobility, and strong interaction between the Ni species and the OMS-2 support. In addition, catalytic mechanisms of the oxidation of three pollutants over 5Ni/OMS-2 were also studied. The oxidation of CO, ethyl acetate, and toluene over the catalysts took place first via the activated adsorption, then intermediates formation, and finally complete conversion of the formed intermediates to CO2 and H2O.
