Elaborately Modified BiVO 4 Photoanodes for Solar Water Splitting

Abstract Photoelectrochemical (PEC) cells for solar‐energy conversion have received immense interest as a promising technology for renewable hydrogen production. Their similarity to natural photosynthesis, utilizing sunlight and water, has provoked intense research for over half a century. Among many potential photocatalysts, BiVO 4 , with a bandgap of 2.4–2.5 eV, has emerged as a highly promising photoanode material with a good chemical stability, environmental inertness, and low cost. Unfortunately, its charge transport properties are modest, at most a hole diffusion length ( L p ) of ≈70 nm. However, recent rapid developments in multiple modification strategies have elevated it to a position as the most…
