High entropy photocatalysts for energy and environmental applications

Abstract

Today, the energy and environmental crisis originating from the use of fossil fuels and carbon dioxide (CO₂) emissions has become a common concern in lives of people. Photocatalysis is a promising clean technology receiving much attention. There are diverse strategies to enhance the efficiency of photocatalysis, and high entropy photocatalysts (HEPs) show great potential as new efficient photocatalysts. The tunability of HEPs provides more possibilities for the design of the electronic structure of the catalysts, which leads to the efficient separation of electron-hole pairs and substantially enhances the photocatalytic performance. This review discusses the composition of HEPs, their advantages in photocatalysis, characterization, and prediction, and the latest applications of various photocatalytic systems. Finally, we discuss and summarize the challenges and the prospects of HEPs.
