▎ 摘　　要

The graphene-like transition metal carbide (Ti3C2X2(X = OH, F)) which was synthesized from etching the layered Ti3AlC2 material was applied as a carrier for depositing Ru nanoparticles (Ru/Ti3C2X2). The as-prepared nanocomposites were characterized by SEM, TEM, XRD, XPS and FTIR. During the hydrolysis process, Ru nanoparticles were uniformly generated on the surface of the carrier and acted as catalysts for the hydrogen generation from hydrolysis of NaBH4 at room temperature. It was found that the catalyst Ru/Ti3C2X2 exhibited excellent catalytic activity toward the hydrolysis of sodium borohydride with a hydrogen generation rate of 59.04 L H-2/g(Ru).min and an activation energy of 22.1 kJ/mol.
