Rational design and application of electrocatalysts based on transition metal selenides for water splitting

Abstract

Transition metal selenides (TMSes) have gained significant attention as viable non-noble metal catalysts for water splitting due to their low cost and potential electrocatalytic activity. However, the electrocatalytic activity of TMSes can be hindered by poor conductivity and limited active sites. To overcome these limitations, numerous TMSe-based electrocatalysts have been recently designed and reported, aiming to optimize their performance. This review provides a comprehensive summary of the recent progress in TMSe-based electrocatalysts for hydrogen evolution reaction (HER), oxygen evolution reaction (OER), and overall water splitting. Additionally, we discuss the various preparation methods and types of TMSe-based electrocatalysts. Furthermore, we outline future perspectives for the advancement of TMSe-based electrocatalysts. Overall, this review aims to offer new insights into the rational design and application of TMSe-based electrocatalysts for efficient water splitting.
