Mechanochemical Synthesis of Pt/NbCT MXene Composites for Enhanced Electrocatalytic Hydrogen Evolution.

Production of hydrogen from water splitting has been considered as a promising solution for energy conversion and storage. Since a noble metal-based structure is still the most satisfactory but scarce kind of catalyst, it is significant to allow for practical application of such catalysts by engineering the heterogeneous structure and developing green and facile synthetic strategies. Herein, we report a mechanochemical ball milling synthesis of platinum nanoclusters immobilized on a 2D transition metal carbide MXene (NbCT) as an enhanced catalyst for hydrogen evolution.
