Summary: The use of well-dispersed nickel catalysts with atomic-scale sizes is an effective approach for maximizing catalytic activity and selectivity for the urea oxidation reaction (UOR). An anodically deposited porous ultrathin film of Birnessite-type manganese oxide on a nickel substrate serves as a catalyst support. The embedded nickel species enhance the catalytic performance and electroactive surface area, leading to improved catalytic rate constant of the UOR.

Summary: In this study, a multifunctional and efficient electrocatalyst P-NiFeOxHy was designed for water electrolysis, which consists of crystalline NiFe phosphide nanocrystals, amorphous P-doped FeOOH, and a crystalline/amorphous heterostructure with superhydrophilic and superaerophobic surface. The optimized design of P-NiFeOxHy showed ultralow overpotentials for oxygen evolution reaction, hydrogen evolution reaction, and urea oxidation reaction. The in-situ Raman spectra and ex-situ XPS analysis were used to investigate the catalytic process and surface structure evolution of P-NiFeOxHy under electrochemical oxidation. Furthermore, P-NiFeOxHy was used as both cathode and anode in a urea-assisted water electrolysis device, which could be driven by a low voltage and even by a solar cell.

Summary: The hydroxyl radicals ('OH) generated on the anode play a crucial role in the electrochemical oxidation (EO) of organic pollutants for water treatment. Inspired by the oxygen evolution reaction (OER), a strategy of anode selection was proposed to stabilize deeply oxidized states ( *O and *OOH) which contribute to the generation of 'OH. Through the use of MIL-101(Cr)-coated-Ti/TiO2 anodes, fast and complete removal of aniline and phenol, as well as improved energy utilization, were achieved compared to undecorated anodes. Mechanistic investigations and density functional theory (DFT) computations further supported the hypothesis and provided insights for the development of anode materials in the EO process.

Summary: An efficient approach is reported to induce the hierarchical self-assembly of perovskite CsPbBr3 nanocrystals by phase transition, which leads to the formation of asymmetric Cs4PbBr6 nanorods with circularly polarized luminescent response. The conversion process from CsPbBr3 nanocubes to Cs4PbBr6 nanocrystals is found to involve an interface phase transition initiated by cysteine molecules. The Cs4PbBr6 nanocrystals then sequentially aggregate to form nanoclusters, which further self-assemble into chiral Cs4PbBr6 nanorods. Molecular dynamics simulations reveal the gradual approach of Cs4PbBr6 nanochains to form an asymmetric structure, supported by the simulated circular dichroism spectrum.

Summary: Nanosized sodium sulfide species greatly enhance the performance of Na-S batteries, but the diminished stability with decreasing cluster size has been rarely considered. This study presents a binary phase diagram of sodium sulfide clusters (NSCs) using an advanced structure search algorithm. The commonly studied monomer model with low sulfur concentrations is energetically unfavorable, thus aggregation of monomers to form multimers is necessary. The relatively stable clusters with low sulfur concentrations, as well as their interaction with carbon-based substrates, are investigated. The findings provide insights into the evolution mechanism of NSCs and the development of high-performance Na-S batteries.
