摘　　要：铜基体上电沉积制得的ＮｉＣｅＰ合金用作析氢电极时，其上的析氢速率比Ｎｉ电极上的析氢速率约大１０ 倍，析氢电势正移２００ 多ｍ Ｖ，表明该电极具有较高的析氢电催化活性。用ＮｉＣｅＰ合金的ＳＥＭThe Ni Ce P alloy was prepared by electrodeposition. Electrocatalytic behaviors of hydrogen evolution on the obtained alloy deposits are studied with cathodic polarization curves in 1 mol·L -1 potassium hydroxide solution. It is shown that the rate of hydrogen evolution on the Ni Ce P alloy is ten times more than that of Ni electrode, and that potential of hydrogen evolution on the cathode of Ni Ce P alloy moves positively compared with Ni cathode, which is over 200 mV for the Ni Ce P alloy at i C =300 mA·cm -2 . The effects of cerium and phosphorus on the electrocatalytic behaviors of hydrogen evolution are also studied by datums of SEM and XPS.
