Abstract

The electrocatalytic performance of commercial PtRu/C is significantly enhanced by directly mixing a few SnO₂ nanoparticles. The composite catalysts show enhanced CO oxidation, higher activity and better stability than commercial PtRu/C. Among the different ratios of SnO₂ nanoparticles (10-40-), the SnO₂-PtRu/C (20-) composite catalyst shows the best catalytic activity for methanol oxidation. The effect of temperature on methanol oxidation was also investigated and the apparent activation energy (E_a) value of catalyst was obtained. The results here suggest a simple route to enhance the catalytic efficiency for commercial PtRu/C catalyst.
