MXene‐supported Ru–Ni: a Common Active Site for Hydrolysis, Hydrogen Oxidation, and Hydrogenation

Insights into the activation and conversion of hydrogen using a single‐mode catalyst is crucial for advancing fuels and fine chemical production. In this paper, the activation and conversion of H2 molecular in hydrogen production and application were investigated on RuM (M = Ni, Co, Cu, Fe)‐MXene catalysts. RuM (M = Ni, Co, Cu, Fe) bimetallic nanoclusters were uniformly distributed on Ti3C2 MXene. The optimal Ru2.5Ni2.5‐Ti3C2 exhibites the highest turnover frequency (TOF) value of 1833 min‐1 toward ammonia borane (AB, NH3BH3) hydrolysis. Meanwhile, the catalysts also showed good catalytic activity in hydrogen oxidation reaction (HOR) and phenylacetylene hydrogenation. The high activity is originl from the acceleration of the catalytic process by RuNi clusters‐Ti3C2 and the promotion of molecular transport by the special interface of RuNi cluster‐MXene. The RuNi clusters‐Ti3C2 with suiable d‐band provide a dependable platform for the regulated activation and conversion of H2 molecules and various reaction intermediates. The competitiveness of nano‐cluster‐MXene catalytic material is showcased for activation and conversion of hydrogen. This research of reaction‐inducing adaptation uncovered the pathway to explore multi‐functional catalysts in energy, chemistry and materials applications.
