Abstract
Rare earth cuprates of composition Ln(2-x),M-x,Cu1-yM'O-y(4-delta) (where L n=La, Nd, Sm and Dy; M=Sr,Ca and Ba; M'=Ru,Sb and Mn; 0.0 less than or equa l toX less than or equal to0.4 and Y=0.1) have been examined as anodes for methanol oxidation These materials display significant activity towards met hanol oxidation in alkaline medium at room temperature. The electrocatalyti c activity for methanol oxidation is higher for noble metals like platinum than that for perovskite oxides. However, latter systems seem to have bette r electrode stability.
