Bi 3 TaO 7 film: a promising photoelectrode for photoelectrochemical water splitting

Most of the transition metal bismuth salts have excellent visible absorption range and carrier transport properties due to their unique structure capable of orbits and s-p bonds. As one of the transition metal bismuth salts, Bi₃TaO₇ is firstly directly prepared on fluorine-doped SnO₂ transparent conductive glass (FTO) as a photoanode for photoelectrochemical (PEC) water oxidation via a simple hydrothermal method using a special precursor …
