摘要

The selection and preparation of electrocatalysts of high performance is one of the most important subjects in the applied researches of electrocatalysis. The common method to obtain electrocatalysts of high performance and low cost is to disperse catalytic materials on supports of carbon or oxides. It is well known that platinum exhibits the best electrocatalytic activity compared with other metals, for which the preparation of electrocatalysts by dispersing platinum on supports has been studied extensively. In recent years big progress has been achieved on the fundamental researches of electrocatalysis by using platinum single crystal as model electrocatalyst, which demonstrates that the atomic arrangements of a surface of platinum is primarily important to determine its activity. The results of this study introduced effectively the possibility of designing and selecting the best electrocatalyst at atomic and molecular level. Owing to the existence of the phenomena of the poly-orientation of a single crystal and mono-orientation of polycrystalline in nature under specific conditions, the possibility mentioned above is more close to the reality. In order to study the surface structure and the electrocatalytic activity at a microscopic level, thestructure of platinized platinum on supports of glassy carbon and the electrocatalytic activity in the oxidation of methanol have been investigated in the present note.
