摘要：

We report the results obtained in the characterization of binary W-Se, Ru-Se as well as ternary W-Ru-Se and Mo-Ru-Se electrocatalysts prepared by screen printing and chemical synthesis. The results indicate that Mo-Ru-Se based catalysts prepared by chemical synthesis possess good electrocatalytic activity for oxygen reduction, The final composition of the compound depends on the starting weight percentage of the carbonyl compounds and the post-preparation processing. As-prepared, Mo-Ru-Se was found to be stable in acid medium (H(2)SO(4)) with high catalytic activity, but after heat treatment the catalytic activity reduced appreciably due to the loss of Se from the compound.
