Summary: A novel strategy was developed to enhance the ORR activity of Co single-atom catalysts by introducing a deformed CoN4 site and Co nanoparticle-CoN4 composite sites, which effectively replenished the total density of CoN4. The resulting concave nanocube-like catalyst exhibited excellent ORR performance and high power density in acidic media, with theoretical studies confirming the enhanced O-2 activation and reduced carbon layer erosion. This research not only provides a new approach to develop ORR catalysts, but also contributes to a deeper understanding of ORR fundamentals.

Summary: Despite extensive research on semiconductor photocatalysis, the fundamental aquatic chemistry of these new materials and their environmental implications are poorly understood. In this study, the solubility of BiVO4 and its non-stoichiometric dissolution in different pH ranges were investigated. The solubility and stability of BiVO4 were found to be pH-dependent, with the lowest solubility and highest stability near pH 5. Illumination significantly enhanced the dissolution of BiVO4. Adsorption of dissolved bismuth by BiVO4 solids was identified as the main reason for the non-stoichiometric dissolution. These findings highlight the importance of considering the dissolution of photocatalysts and provide a method to evaluate the environmental stability and risks of other semiconductor materials.

Summary: In this study, a BiVO4/CuBi2O4/Co-Pi photoanode was prepared to enhance the photoelectrochemical water splitting performances. It was found that the heterojunction structure of CuBi2O4 and BiVO4 widened the absorption range of light and accelerated the separation of photogenerated carriers. The presence of Co-Pi constituent as a water oxidation catalyst further improved the interface charge transfer and increased the active surface area. The results showed that the ternary semiconductor structure can greatly enhance photoelectrochemical performance, making it a promising strategy for the development of photoelectrochemical water splitting.

Summary: Photocatalysis offers an energy-efficient and environment-friendly route to alleviate energy crisis and environmental pollution. In this paper, the effects of various factors on dual-functional photocatalytic activity are discussed, including photocatalyst types, composites, microstructure, pollutants properties, co-existing substances, and different synergistic targets. The balance between water remediation and H2 production in a synergistic system requires a bi-directional adaptation of catalyst and pollutant, as well as a comprehensive consideration of the reaction environment. Developing efficient components and suitable methods, constructing optimized catalyst structures, and clarifying the degradation mechanism of pollutants are crucial for efficient photocatalytic synergistic systems. This work provides a theoretical basis for the development of bifunctional photocatalytic systems.

Summary: Measurement of dissolved ozone concentration is crucial for ozone treatment. A conventional indigo method is commonly used, but it becomes difficult when water contains substances that react with C-C double bonds other than ozone. To address this concern, we developed a breakthrough method to measure ozone concentration by measuring the p-formylbenzoic acid (p-FBA) produced after the reaction of p-vinylbenzoic acid and ozone. Our new method contributes to extensive ozone treatment and ozonation management.
