N2 - High-entropy oxides, composed of five or more major cations and oxygen, represent diverse functional applications including photocatalysis and electrocatalysis. In this work, a high-entropy oxide is synthesized and used as a photoanode for photoelectrocatalysis. The oxide demonstrates efficient light absorbance, low electron/hole combination and enhanced photocurrent generation. The material exhibits a remarkable hydrogen production from water exceeding the activity of the P25 TiO2 photocatalyst. These achievements underscore the promise of high-entropy materials as new candidates for photoelectrocatalytic applications.
