Abstract

Abstract: Four kinds of rare earth metal Ions(Y³⁺, Tb³⁺, Eu³⁺ and Pr³⁺) were appended into the methanol aqueous solution respectively as an additive and the cyclic voltammograms of the aqueous solutions were studied. The results show that Y³⁺ and Tb³⁺ had an obvious promotion effect on the electro-oxidation of methanol. The additives Y³⁺ and Tb³⁺ could improve the methanol anodic oxidation current by 85%, and Eu³⁺ and Pr³⁺ had little promotion effect on the electro-oxidation of methanol. The results also show that the promotion effect of the rare earth metal ions were related with the electronic distribution of these elements and their adsorption on the Pt electrode surface.

Key words: Methanol, Electrochemical oxidation, Rare earth element, Promoting agent
