Abstract
The hydrogen evolution reaction (HER) is an important energy conversion process that underpins many clean energy technologies including water splitting. Herein, we report for the first time the application of two-dimensional (2D) layered transition metal carbides, MXenes, as electrocatalysts for the HER. Our computational screening study of 2D layered M2XTx (M = metal; X = (C, N); and Tx = surface functional groups) predicts Mo2CTx to be an active catalyst candidate for the HER. We synthesized both Mo2CTx and Ti2CTx MXenes, and in agreement with our theoretical predictions, Mo2CTx was found to exhibit far higher HER activity than Ti2CTx. Theory suggests that the basal planes of Mo2CTx are catalytically active…
