摘　　要：研究了在用活性沉积方法制备的Ｐｔ／Ｃｏ极上的析氢反应。在室温下负载量为１０ｍｇ／ｃｍ＾２的Ｐｔ／Ｃｏ在７ｍｏｌ／Ｌ ＫＯＨ溶液中以１Ａ／ｃｍ＾２电流密度析氢的过电位小于１５０ｍＶ。初步研究发现了Ｐｔ／Ｃｏ电极用表面薄层Ｎａｆｉｏｎ膜修饰能大大提高其使用稳定性。The hydrogen evolution on reactively co-deposited Pt/Co electrodes in 7mol/L KOH solution has been studied. For a reactively co-deposited Pt/Co electrode (loading:10mg/cm￣2). the measured over-potential for hydrogen evolution was less than 150mV at room temperature and 1A/cm￣2 current density. Preliminary study showed that and the modification of Pt/Co electrode by a thin Nafion film on the surface can greatly increase the operating life of the electrode.
