Electrodeposited cobalt phosphide superstructures for solar-driven thermoelectrocatalytic overall water splitting

Author affiliations

Abstract

We demonstrate solar-driven thermoelectrocatalytic water splitting using unique cobalt phosphide (Co2P) sheet-on-leaf superstructures. Co2P is synthesized through a one-step room-temperature electrodeposition technique that precludes the release of toxic PH3 gas, where the in situ process warrants electron and mass transfer between Co2P and the underlying substrate for effective electrocatalytic reactions. Facilitated by thermionic energy harvested from sustainable solar irradiance conversion, the electrocatalytic behaviours of Co2P are remarkably increased. These superstructures are endowed with a higher electrical conductivity and electrochemical surface area, reduced activation energy and enhanced solar-to-heat conversion efficiency to accelerate electrocatalysis.
