Summary: Enhanced visible light-driven pseudocapacitance response is achieved by synthesizing Ni-doped BiOBr nanosheets via a facile precipitation method. The doping of Ni atoms onto the BiOBr structure expands the light absorption range and improves photogenerated carrier separation efficiency. The Ni-BiOBr photoelectrode exhibits a significantly higher specific capacitance under UV light compared to dark conditions. Moreover, the Ni-BiOBr//reduced graphene oxide asymmetric supercapacitors demonstrate excellent energy density and capacitance retention under light irradiation.

Summary: Metal-air batteries generate electrical energy by combining metal and oxygen, and they are considered a promising technology due to their high energy density, low cost, and environmental friendliness. However, the difficulties in decomposing the discharge products result in a high overpotential. Recent research has shown that semiconductors can capture solar energy and improve the battery reaction by increasing electron migration rate. This review paper discusses the fundamentals of photoelectrochemistry, photocathode design principles, various photocatalysts, challenges caused by light, and perspectives for the development of high-performance light-assisted metal-air batteries.

Summary: Solar-to-electrochemical energy storage is an important solar utilization technology, which includes solar cell and photocatalysis cell. While integrated solar batteries achieve indirect solar energy storage, the emerging coupled solar batteries allow direct solar energy storage. However, issues of rapid charge recombination and misaligned band energy have hampered the efficiency and development of coupled solar batteries. This review discusses the design of photoelectrochemical storage materials and coupled solar batteries to promote coupling between photogenerated charges and redox reactions for high efficiency, along with opportunities for new devices with matched band alignments.

Summary: In this study, a strategy of utilizing the Mott-Schottky effect to regulate electron distribution is demonstrated for developing an effective electrocatalyst for hydrogen evolution in acid electrolyte. The hybrid Ru-WO(2.72) catalyst exhibits superior activity, with the Ru-based mass activity 161.6 times higher than that of commercial Ru/C. The enhanced hydrogen production is attributed to the electron enrichment induced by the Mott-Schottky effect at the metal-metal oxides interface.
