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.

Ultrafast Charge Carrier Dynamics in CuWO₄ Photoanodes [PDF]

The Journal of Physical Chemistry C, 2021
CuWO4 is a ternary metal oxide semiconductor with promising properties for photoelectrochemical (PEC) water splitting and solar light conversion, due to its quite low band gap (2.3 eV) and high stability in an alkaline environment. Aiming at understanding the origin of the relatively low PEC efficiency attained with CuWO4 photoanodes, we here ...
