The theory-guided synthesis of a tungsten-based W2TiC2Tx MXene from a non-MAX nanolaminated ternary carbide (W,Ti)4C4−y is reported. The tungsten-rich basal plane of the W2TiC2Tx MXene is then examined for the electrocatalytic hydrogen evolution reaction using a combined experimental and theoretical approach.
