This study explores the use of metal/MXene-based materials for energy conversion, particularly focusing on a novel method for synthesizing a CoIr nanoalloy catalyst using Lewis acidic molten salt to etch a MAX precursor.
The resulting CoIr/MXene catalyst exhibits excellent hydrogen evolution reaction (HER) performance with minimal overpotentials and high stability, outperforming commercial catalysts in alkaline media.
This research highlights the advantages of the molten salt etching technique in synthesizing a highly efficient catalyst and contributes to the development of advanced metal/MXene-based materials for energy applications.
