BiVO₄ Photoanodes Enhanced with Metal Phosphide Co‐Catalysts: Relevant Properties to Boost Photoanode Performance

Small, 2023
AbstractAchieving highly performant photoanodes for oxygen evolution is key to developing photoelectrochemical devices for solar water splitting. In this work, BiVO4 photoanodes are enhanced with a series of core–shell structured bimetallic nickel‐cobalt phosphides (MPs), and key insights into the role of co‐catalysts are provided.

BiVO4 Ceramic Photoanode with Enhanced Photoelectrochemical Stability [PDF]

Nanomaterials, 2021
Monoclinic bismuth vanadate (BiVO4) is an attractive material with which to fabricate photoanodes due to its suitable band structure and excellent photoelectrochemical (PEC) performance. However, the poor PEC stability originating from its severe photo-corrosion greatly restricts its practical applications.
