Doping effect of transition metals in Raney Ni catalyst was investigated by measuring of benzene hydrogenation activity and hydrogen content stored inside the catalyst. The catalyst doped with Ti showed the best catalytic activity of all among the used dopants, and the optimum Ti content in a starting alloy was 1.5wt%, and for the electrochemical reaction it was 2.0wt%. Surface analysis by means of EDS revealed that most of doped Ti was concentrated on the surface of catalyst. The Al leaching mechanism from Raney alloy was selective dissolution. The catalytic activity of Raney Ni was affected cconsiderably by hydrogen pretreatment temperature, and the adequate PTFE content for dispersing catalyst particles was 5wt%.
