Summary: Transition metal compound catalysts with high efficient and stable performance have attracted extensive attention of researchers. In this study, dual cation doped Ni3S4 nanosheets loaded on nickel foam were prepared by two step hydrothermal method. Co and Fe dual doping can induce the internal electronic interaction of the catalyst, thus exposing more active sites. The electrochemical test results show that Co and Fe doped Ni3S4 have better electrocatalytic performance for oxygen evolution than single cation doped and pure Ni3S4.

Summary: The key step for water splitting is the oxygen evolution reaction, which requires an efficient catalyst. Molybdenum disulfide is a promising doping platform for developing high-performance OER catalysts. In this study, MoSx nanowires doped with Fe/Co/Ni ternary transition metal were prepared on an iron-nickel alloy foam through a simple in-situ hydrothermal method. The resulting Fe/Co/Ni-MoSx/INF self-supported electrode exhibited excellent OER activity, with small overpotentials of 214 and 263 mV at current densities of 10 and 100 mA/cm2, respectively. The catalyst also showed good stability during 20 hours of continuous operation. This work contributes to the development of efficient OER catalysts based on transition metal-doped MoSx and provides an alternative to noble metal catalysts.

Summary: Solar water purification technology is an effective and affordable method for obtaining fresh water. However, the efficiency of purification is limited by high ion concentration, organic pollution, and biological pollution. In this study, a porous hydrogel membrane (Fe/TA-TPAM) was developed for the purification of contaminated water. The membrane has good light absorption and photothermal conversion abilities, resulting in high evaporation rates and solar efficiency. With the addition of tannic acid (TA) and Ti3C2 MXenes, the Fe/TA-TPAM membrane exhibits satisfactory purification properties for organic-contaminated and biologically contaminated water. These findings provide a novel strategy for designing advanced photothermal conversion membranes for water purification.

Summary: ZnO nanosheets, 2D/1D ZnO/CdS hybrid, and ternary ZnO/CdS/GO S-scheme heterojunction photocatalyst were fabricated using a low-temperature hydrothermal technique. The addition of CdS and GO significantly improved the photocatalytic activity of ZnO, as demonstrated by the higher dye degradation rate constant and the increased visible light absorption. CdS also regulated the size and distribution of ZnO nanosheets, increasing the specific surface area of the sample. The presence of CdS and GO promoted the rapid separation of photoexcited carriers in ZnO, and GO further enhanced the transmission rate of electrons and the photoelectric stability of the ZnO/CdS heterogeneous photocatalyst.

Summary: Deciphering the metal-support interaction in Fenton-like catalysis on millimeter-scaled catalysts is challenging but highly desirable. In this study, we fine-tune the support-surface reconstruction of Co2AlO4 on gamma-Al2O3 millispheres and reveal the origins of its activity in peroxymonosulfate activation. We find that the formation of Co2AlO4 with coordinated Co3+/Co2+ redox centers is regulated by the reconstructed tetrahedral and pentacoordinate Al3+ as binding sites, via strong metal-support interactions.

Summary: In this study, dual metal catalysts with different non-metals dispersed in a graphene frame were computationally designed, and five candidates with promising catalytic performance for nitrogen reduction reaction (NRR) were identified. These catalysts can effectively decrease the onset potential of NRR and suppress the competitive hydrogen evolution reaction. The excellent catalytic performance is attributed to the synergetic effects of metal-metal and metal-ligand interactions, which can activate the N=N bond and improve the efficiency and selectivity of ammonia synthesis.

Summary: This study investigates the origin of the high activity of electrodeposited Ni/Ru hydroxide hybrid nanoparticles in nitrate electro-reduction reaction (NITRR). It is found that the interaction between Ru and the nickel substrate formed during electrodeposition plays a crucial role in the high activity. The introduction of moderate oxidized nickel layers enhances the interaction between Ru and Ni, leading to improved nitrate-to-ammonia conversion, while excessive oxidized nickel layers deteriorate the catalytic performance.
