Hydrogen (H2) production through water splitting using sustainable energy sources is gaining increasing attention. However, limited catalytic performance based on a single driving force presents both opportunities and challenges for achieving a high-efficiency H2 output. Exploring multiple driving sources to enhance the comprehensive catalytic performance shows great promise. BiFeO3 (BFO), with features of narrow band gap and ultrahigh ferroelectric polarizations, is considered as a promising alternative candidate for green H2 production from water splitting. However, the inherent overpositive...

Hydrogen peroxide (H2O2) is a valuable chemical for a wide variety of applications. The environmentally friendly production route of the electrochemical reduction of O2 to H2O2 has become an attractive alternative to the traditional anthraquinone process. The efficiency of electrosynthesis process depends considerably on the availability of cost-effective catalysts with high selectivity, activity, and stability. Currently, there are many outstanding issues in the preparation of highly selective catalysts, the exploration of the interface electrolysis environment, and the construction of electr...

Fast charging and high volumetric capacity are two of the critical demands for sodium-ion batteries (SIBs). Although nanostructured materials achieve outstanding rate performance, they suffer from low tap density and small volumetric capacity. Therefore, how to realize large volumetric capacity and high tap density simultaneously is very challenging. Here, N/F co-doped TiO2/carbon microspheres (NF-TiO2/C) are synthesized to achieve both of them. Theoretical calculations reveal that N and F co-doping increases the contents of oxygen vacancies and narrows the bandgaps of TiO2 and C, improving th...
