MXenes as electrocatalysts for hydrogen production through the electrocatalytic water splitting process: A mini review

Abstract

Hydrogen is a promising alternative to fossil fuels for energy production, but challenges persist in various aspects of hydrogen technology. MXenes, a category of two-dimensional materials comprising transition metal carbides, nitrides, and carbonitrides, have emerged as potential electrocatalysts for the hydrogen evolution reaction (HER) through water splitting. This review provides a concise overview of MXenes, encompassing their structure, properties, and commonly employed preparation methods. It discusses the fundamental principles of the water splitting process, including the reaction mechanism and evaluation criteria for HER performance. The review summarizes recent studies on MXenes and MXene-based materials as electrocatalysts for HER, highlighting their electrocatalytic capabilities. Additionally, it examines the current challenges and emerging possibilities associated with MXenes-based electrocatalysts. By providing a holistic understanding of MXenes and their potential in catalyzing hydrogen production through water splitting, this review serves as a valuable reference for the development of advanced electrocatalysts based on MXenes.
