将层状Ti3AlC2材料蚀刻合成的类石墨烯过渡金属碳化物（Ti3C2X2(X = OH， F)）作为沉积Ru纳米粒子（Ru/Ti3C2X2）的载体。采用SEM、TEM、XRD、XPS和FTIR对所制备的纳米复合材料进行了表征。在水解过程中，Ru纳米颗粒均匀地在载体表面生成，并作为室温下NaBH4水解制氢的催化剂。结果表明，Ru/Ti3C2X2催化剂对硼氢化钠的水解具有良好的催化活性，产氢率为59.04 L H-2/g（Ru）。min，活化能22.1 kJ/mol。Copyright (C) 2014, Hydrogen Energy Publications， LLC.由Elsevier Ltd.出版。版权所有。
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.
