Facile preparation of nickel phosphide for enhancing the photoelectrochemical water splitting performance of BiVO₄ photoanodes

Abstract

Herein, nickel phosphides with different stoichiometry (Ni2P and Ni12P5) were successfully modified on the surface of BiVO4 photoanode for enhancing the PEC water splitting performance.

Enhanced solar-driven photoelectrochemical water splitting using nanoflower Au/CuO/GaN hybrid photoanodes

“…7,8 The primary challenges with regard to photoelectrode materials, which must be solved for the actual implementation of PEC water splitting include the efficiency and stability of the photoelectrode. 9,10 Transition metal oxides, 11,12 phosphides, 13,14 suldes, 15 hydroxides, 16 and carbides 17 are commonly employed in the PEC water-splitting process. However, these materials have poor crystal quality, short carrier lifetime, broad band gap and short diffusion length of charge carriers, which all contribute to their poor performance as photoelectrodes in the PEC water-splitting process.…”
