摘　　要：采用浸渍-热分解法制备了一种纳米Ni/Y2O3催化剂,并应用X射线衍射、BET比表面测试分析手段对该催化剂的结构性能进行了表征,采用固定床反应器对催化剂的催化性能进行测试。结果表明:该催化剂对乙醇的水蒸气重整反应表现出较高的活性和稳定性,可作为燃料电池氢源技术中乙醇重整器的候选催化剂。A catalyst of Ni nanoparticles supported on Y2O3,which was prepared by the impregnationhot decomposition,was studied.The structural properties of the catalysts were tested through X ray diffraction and BET area test.The catalytic properties of the catalyst were tested through a fix bed reactor,and it shows a high activity for the ethanol steam reforming with a high conversion of ethanol.The catalyst has long term stability for the steam reforming of ethanol,and it's therefore a good choice for ethanol processors in fuel cells.
