一、绪言电极材料在电解反应中是整个电化学现象的一个非常重要的支配因素。因此电极材料在电化学中历来是一个重要的研究课题。至今已开发了很多新的电极材料。但是,一般作为实用的电极材料只是金属(包括合金)、金属化合物(主要是导电氧化物)和碳(石墨)等。近年来还开发了半导体材料。对电极材料不能仅仅单纯的从导电性物质来考 I. INTRODUCTION Electrode materials in electrolysis reaction is a very important dominating factor of the whole electrochemical phenomenon. Therefore, electrode materials in the electrochemical has always been an important research topic. To date, many new electrode materials have been developed. However, as a practical electrode material, only metals (including alloys), metal compounds (mainly conductive oxides), and carbon (graphite) are generally used. In recent years, semiconductor materials have also been developed. Electrode material can not be purely from the conductive material to test
