Abstract ：
Highly active, stable, economic friendly electrocatalysts play a crucial role for the commercialization of direct methanol fuel cells (DMFCs). One kind of flower-like PtNi bimetallic particle anchored on TiO2 na-notube arrays (PtNi/TNTs/Ti) had been synthesized by one-step electrochemical synthesis as anode catalysts for methanol oxidation reaction (MOR) in this study. The PtNi/TNTs/Ti electrode demonstrated high elec-trocatalytic activity and durability significantly for MOR. In addition, PtNi100/TNTs/Ti possessed a mass activity of 409.8 mA/mgpt, which was four times greater than that of Pt100/TNTs/Ti electrodes. According to further structure analysis, the improvement in catalytic activity was attributed to lattice compression when Ni atoms entered the Pt lattice accompanied by a 1.02 eV positive shift in Pt 4 f7/2 binding energy, and density functional theory (DFT) calculations indicated that the remarkably enhanced catalytic performance on PtNi through lattice compression arising from the enhanced OH adsorption. It appears promising that this simple method could be adopted to prepare an integrated electrode used as energy and environmental applications. (c) 2023 Published by Elsevier B.V.

Abstract ：
Rechargeable aluminum batteries (RABs), with abundant aluminum reserves, low cost, and high safety, give them outstanding advantages in the postlithium batteries era. However, the high charge density (364 C mm(-3)) and large binding energy of three-electron-charge aluminum ions (Al3+) deintercalation usually lead to irreversible structural deterioration and decayed battery performance. Herein, to mitigate these inherent defects from Al3+, an unexplored family of superlattice-type tungsten selenide-sodium dodecylbenzene sulfonate (SDBS) (S-WSe2) cathode in RABs with a stably crystal structure, expanded interlayer, and enhanced Al-ion diffusion kinetic process is proposed. Benefiting from the unique advantage of superlattice-type structure, the anionic surfactant SDBS in S-WSe2 can effectively tune the interlayer spacing of WSe2 with released crystal strain from high-charge-density Al3+ and achieve impressively long-term cycle stability (110 mAh g(-1) over 1500 cycles at 2.0 A g(-1)). Meanwhile, the optimized S-WSe2 cathode with intrinsic negative attraction of SDBS significantly accelerates the Al3+ diffusion process with one of the best rate performances (165 mAh g(-1) at 2.0 A g(-1)) in RABs. The findings of this study pave a new direction toward durable and high-performance electrode materials for RABs.

Abstract ：
Electrode design plays an important role in improving hydrogen evolution reaction (HER), and the self-supporting electrode with three-dimensional (3D) porous structure is widely adopted in the electrocatalytic hydrogen evolution. To better the performance of Pt catalyst for hydrogen evolution, a layer of TiO2 nanotube arrays (TiO2 NTs) fabricated on titanium mesh (3D-Ti) or plate Ti (P-Ti) substrate, respectively, has been selected as support materials to load Pt nanocluster (Pt-x/TiO2 NTs@3D-Ti and Pt-x/TiO2 NTs@P-Ti) via an atomic layer deposition method. It has been revealed that one chemical bond of Ti-O-Pt had been formed between Pt nanocluster and TiO2 nanotube. The theoretical calculations confirm that Ti-O-Pt bond can not only improve the stability of Pt nanocluster but also improve its capability for hydrogen evolution. In addition, the 3D-Ti substrate with open structure can further better Pt nanoclusters' performance on hydrogen evolution. The obtained Pt-x/TiO2 NTs@3D-Ti electrode exhibits an overpotential of 53 mV in 0.5 M H2SO4 at -10 mA cm(-2), and its mass activity has been improved by a factor of 18 compared with Pt-x/TiO2 NTs@P-Ti.

Abstract ：
2H phase molybdenum disulfide (2H-MoS2) possesses the two-dimensional layered structure and high theoretical capacity, presenting excellent lithiation-delithiation property. However, the violent capacity decay within dozens of cycles still remains a great challenge due to lacking of in-depth failure mechanism. Herein, a novel decay-recovery-decay failure phenomenon upon long-term cycles is reported for the first time, which originates from the slow size change of Mo nanoparticles (NPs). Decay stages are triggered by many irregular-shaped Mo NPs with the increasing size up to similar to 15 nm, leading to prominent pseudocapacitance failure and capacity loss. Subsequent recovery stages are attributed to the pulverization of coarse Mo NPs through surface sulfurization and accompanying lithiation. To overcome the instability issue, proper modifiers should be introduced to restrain the spontaneous growth of Mo NPs, such as aluminum oxide (Al2O3). The strong Mo-Al2O3 bond gradually "drags" Al2O3 fragments into the active material as the cycle continuously proceeds, resulting in the efficient refinement and the reversible conversion between Mo and MoS2. Therefore, the enhanced cycling stability and the capacity retention are successfully achieved. It is expected to provide a new insight into the energy storage of transition metal chalcogenide anode materials in rechargeable batteries.

Abstract ：
An innovative method is created for transforming iron-rich RO phase (MgO0.239FeO0.761) on steel slag surface into nanostructured Mg0.04Fe2.96O4 layer. The phase change process is investigated, and it is found that salicylic acid modification and alkaline roasting procedures remarkably increase the specific surface area from 0.46 m2/g (raw steel slag) to 69.5 m2/g (Mg0.04Fe2.96O4), and the generation of Mg0.04Fe2.96O4 enhances the absorption of visible light and Cr(VI) conversion with 2-times increasement than raw steel slag. Surface complexation between H2C2O4 ligands and Fe metal moiety on Mg0.04Fe2.96O4 induces the intramolecular electron transfer under visible light irradiation based on a ligand-to-metal charge transfer mechanism, thus resulting in Cr(VI) photoreduction, and the catalytic efficiency is above 90% for Cr(VI) (40 mg/L) under inherent pH= 5.5 conditions. Moreover, recyclability tests based on magnetic separation show that the photoreactivity is closely related to Mg content of Mg0.04Fe2.96O4 layer where Mg leaching occurs and finally generates cubic spinel configuration Fe3O4. This work highlights the importance of surface functionalization in post-use phases of steel slag in which surface reactivity and application potential can be greatly altered by chemical exposure history and surface transformations. It also provides valuable references for studying the metastable state mechanism of magnesium ferrite photocatalysts.

Abstract ：
Wearable flexible devices require advanced lithium-ion batteries (LIBs) for energy supply, thus promotes the development of self-assembled, binder-free, film-type anodes with the advantage of no additives, strong binding force and low contact resistance. Among many potential candidates, 2H phase molybdenum disulfide (2H-MoS2) has been attracting much attention due to its high practical capacity and graphene-like structure. However, few interests are paid to the compactness design inside the in-situ grown MoS2 film on bendable matrices, leading to poor structure stability and low volumetric capacity. Herein, film compactness is carefully modulated by controlling the sputtering parameters, then the cross-section microstructure and electrochemical property are systematically investigated. Among them, the dendritic-arranged, middle porosity MoS2 (MP-MoS2) offers abundant Li-ion migration channels, delivering an enhanced charge-discharge capacity of 1136 and 1157 mAh center dot g(-1) (similar to 3.7 Ah.cm(-3)) after 300 cycles at 1C. MP-MoS2 (2 h) with the same structure and increased mass loading can also stably operate for 400 cycles without decay. Notably, it remains stable cycling on titanium and stainless-steel matrices, but the sharp decay often occurs within tens of cycles towards common copper foil due to Cu diffusion and film orientation alteration, implying that low-melting-point flexible matrices are not suitable for in-situ 2H-MoS2 assembling at high temperature. This work provides a practical analyzation strategy for designing film-type 2H-MoS2 anode material used as flexible LIBs.

Abstract ：
Aluminum alloys are widely used in the aerospace and automotive industries due to their high strength and low density but also suffer from poor wear resistance. The employment of stable solid lubricants on aluminum alloys will be beneficial for their service life under load-bearing conditions. In this paper, MoSx-W composite coatings were deposited on porous anodic aluminum oxide (AAO)/Al substrates. The effects of tungsten content on the film structure and friction properties were systematically investigated. It is found that tungsten exists as metallic particles within the MoSx matrix, forming a system of hardness phase reinforced soft matrix. With the increase of W content, the film morphology transforms from nano-flower-like to ball-like, associated with an obvious enhancement of film density as well as hardness. The latter prolongs the service life of MoSx films from 10 min only in untreated specimen to 88.8 min in composite sample. Finally, the improvement of wear performance upon tungsten loading was discussed in detail.

Abstract ：
Here, Pt modified anatase-type titanium dioxide (TiO2) nanotube arrays were prepared by electroplating method for a low-platinum Pt/TiO2 nanotubes electrode (Pt/TiO2-NTs). By contrast, we fixed Pt on TiO2 dense film by the same procedure as a control sample (Pt/TiO2-F). The scanning electron microscopy and transmission electron microscopy observation showed that Pt nanoparticles were distributed uniformly in nanotube arrays, and Pt/TiO2 NTs showed a higher efficiency in electrocatalytic hydrogen evolution compared with Pt/TiO2-F and commercial Pt/C catalyst, in which the overpotential of Pt/TiO2-NTs was 0.079 V, the Tafel slope was 42.7 mV.dec(-1) at 10 mA.cm(-2). The catalytic activity of 3 000 cycles duration stability test results showed that Pt/TiO2-NTs exhibited excellent stability compared with the above contrast electrodes.
