The Catalytic Behavior for Ni-W Electrode Modified by Carbon Ion Beam Implantion

镍基溅射钨注碳电极的催化性能张季爽，吕瑶姣，李青莲（湖南大学化学化工系环境工程系，长沙４１００８２）沈报恩（杭州大学化学系，杭州３１００２８）析氢反应研究涉及到氢能、燃料电池、氯碱工业等的能源开发及节能技术，并具有重要的理论意义￣［１～５］．本工作研...The hydrogen evolution activity in acidic and basic mediums for Ni-W electrodemodified by carbon ion beam implantation was investigated.The experimental results show thiselectrode has superior catalytic activity for the hydrogen evolution reaction than that of the unmodifiedNi-electrode.Long period testing of electrolysis under high current density show that this electrode hasalonger useful life hence it is a practical electrode material.The temperature effect of electrocatalyticproperty was also inverstigated.The experimental regularities are explained on the basis of the formation of surface m uItialloys of Ni-W-WC.作者联系地址：湖南大学化学化工系环境工程系，杭州大学化学系，西安２１３研究所Author's Address: Department of Chemistry and Chemical Engineering,Hunan University,Changsha 410082Shen BaoenDepartment of Chemistry,Hangzhou University,Hangzhou 31002
