Summary: A single-crystal BiVO4 photoanode with surface nanostructure was prepared using a low-cost and simple etching process, leading to higher photocurrent density and lower onset potential. This improvement can be attributed to the larger electrochemical active surface area and abundant oxygen vacancies on the surface.

Summary: Monoclinic bismuth vanadate (BiVO4) is a promising material for photoanodes due to its suitable band structure, but its poor PEC stability limits its practical applications. This study investigated Mo-doped BiVO4 ceramics as photoanodes and found that Mo-BVO (C) exhibited enhanced PEC stability compared to Mo-doped BiVO4 films, potentially offering a novel ceramic design for improving the stability of BiVO4 photoanodes.

Summary: The study reports the unexpectedly improved photoelectrochemical activity and stability of the Ta3N5 photoelectrode in acidic electrolytes. It reveals the oxidation mechanism of Ta3N5 surface as transpassivation, with suppressed surface oxidation rate under acidic pH conditions. The less formation of the passive layer at the Ta3N5 surface leads to improved photoelectrochemical activity and stability.

Summary: Tantalum nitride (Ta3N5) is a promising photoanode material, but its material quality has been a challenge. Defects in Ta3N5 thin films affect their performance and accelerate degradation in water during electrochemical applications. This study experimentally examines the distribution of trap states in Ta3N5 thin films and proposes a targeted passivation strategy to suppress defects and enhance performance. The findings provide valuable insights for the integration and development of high-performance Ta3N5 thin film devices.

Summary: The combination of boron-treated BiVO4 with NiFeOx electrocatalyst (NiFeOx/B/BiVO4) demonstrates excellent performance as a photoanode under solar illumination, achieving high current density at lower voltages without the need for sacrificial agents. This is largely attributed to the presence of [B(OH)4](-) ligands and NiFeOx electrocatalysts, which enhance the separation efficiency of photoelectron-hole pairs. This work provides a promising approach for developing efficient photocatalysts for solar water splitting.

Summary: In this study, an efficient strategy for boosting bulk charge transport of BiVO4 through impregnation of BiVO4 in BiOI nanosheets precursor solution was demonstrated. The introduction of oxygen vacancies in the bulk of BiVO4 and the built-in electric field in BiVO4-BiOI synergistically improved the photocurrent density. This facile impregnation strategy is believed to pave an alternative way to the development of highly efficient BiVO4 photoanode.
