BiVO 4是一个有吸引力的候选人，被用作太阳能水分解的光阳极。然而，其光电化学（PEC）性能受到体相和界面电荷转移能力的限制。在这项研究中，我们通过引入氧空位Ar等离子体处理加速体电荷转移和促进界面载流子转移负载的WCoFe羟基氧化物电催化剂。与单独修饰的改善结果相比，实现了更大的增强，并且在磷酸钾（KPi）缓冲溶液中在光照射下获得5.49 mA/cm 2的光电流。结果表明，通过引入氧空位和负载电催化剂等有利因素的协同作用，提高了BiVO 4基薄膜光阳极的光电转换性能。
BiVO4is an attractive candidate that is used as a photoanode for solar water splitting. Unfortunately, its photoelectrochemical (PEC) performance is restricted by the slow charge transfer ability in the bulk and the interface. In this study, we accelerated bulk charge transfer via introducing oxygen vacancies by Ar plasma treatment and facilitated interfacial carrier transfer by loading a WCoFe oxyhydroxide electrocatalyst. A larger enhancement was achieved compared to the improvement results from the individual modification, and a photocurrent of 5.49 mA/cm2was obtained under light irradiation in a potassium phosphate (KPi) buffer solution. The results demonstrate that the PEC performance of the BiVO4-based film photoanode is enhanced by integrating synergy effects of favorable factors by introducing oxygen vacancies and loading electrocatalysts.
