摘要

The bismuth vanadate semiconductor photocatalyst has attained special consideration in various electrochemical applications owing to its favorable optical configuration and distinctive electronic properties. In the quest of developing efficient and sustainable photoelectrochemical technology to generate hydrogen by water splitting, the monoclinic scheelite BiVO4 is the intrinsic choice due to its highlighted strong photo activity in the visible light region. The current chapter attempts to summarize the fundamentals of structure and properties of BiVO4 crystal along with the strategies followed to achieve desired photocurrent density, leading to hydrogen production by BiVO4 for sustainable practical application. This chapter discusses the recent approaches such as band gap engineering by multi-elemental doping, optical properties tuning by nanostructuring, bulk and surface charge transport improvement by heterojunction, and surface catalyst adopted to develop high-performance BiVO4-based photoanode.
