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 are crucial for advancing fuels and fine chemical production. In this paper, the activation and conversion of H₂ molecules 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 Ru_2.5Ni_2.5-Ti₃C₂ exhibits 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 originates from the acceleration of the catalytic process by RuNi clusters-Ti₃C₂ and the promotion of H₂ molecular transport by the special interface of RuNi cluster-MXene. The RuNi clusters-Ti₃C₂ with multisites provide a dependable platform for the regulated activation and conversion of H₂ molecules and various reaction intermediates. The competitiveness of nanocluster-MXene catalytic material is showcased for activation and conversion of hydrogen. This research of reaction-inducing adaptation uncovered the pathway to explore multifunctional catalysts in energy, chemistry, and materials applications.
