The Electrode Process of Some Organic Dyes Studied by Spectroelec tro chemical Technique in Situ

原位光谱电化学技术对有机染料分子电极过程的研究①唐寅轩杨杭生沈报恩＊（杭州大学化学系杭州３１００２８）有机染料分子修饰电极在光电化学，电催化等方面的应用均有较好的效果，因而受到人们极大的注意．近年来已经制备成功许多染料化学修饰电极［１］．原位光谱电化...Spectroelectrochemistry especially with in situ measurement in a cell provides a very useful mthodology for measuring the parameters of electrode process. In this paper, we report the determination of formal potentials, the number of electron transfer, the diffusion coefficient, the heterogeneous electron transfer rate constant and the transfer coefficient of some organic dyes (Methyelene blue, Neutral red, Indigo carmine) using spectroelectro chemical technique in situ.作者联系地址：杭州大学化学系Author's Address: Dept.

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
