Recent progress on high-entropy materials for electrocatalytic water splitting applications

Abstract

Advanced materials for electrocatalytic water splitting applications have been sought-after considering both environmental and economic requirements. However, the traditional materials design concept limits the exploration of high-performance catalysts. The born of a materials design concept based on multiple elements, high-entropy materials, provides a promising path to break the shackles of compositional design in materials science. A number of high-entropy materials were reported to show remarkable properties for electrocatalytic water splitting applications. High-entropy materials were widely confirmed to be one kind of the best electrocatalysts for water splitting applications. Due to the synergy of multiple metal components, they show excellent catalytic activity. Several nontraditional methods were developed and reported to prepare high-performance high-entropy materials. This review article presents the recent progress on high-entropy materials for electrocatalytic water splitting applications. Moreover, it presents the research interests and future prospects in this field.
