摘要：
The previous conclusion that the redox couple of Mo(III)/Mo(IV) plays a key role in the enhancement of the catalytic activity of the Pt electrode was confirmed even at a high temperature of 80°C. An extended analysis of voltammograms to the electrode coadsorbed with molybdenum and methanol species showed that the highest oxidation current is obtained at an equal coverage of the molybdenum and methanol species. The bifunctional mechanism was discussed. © 1990.
