Effect of PtRu alloying degree on electrocatalytic activities and stabilities

▶ PtRu alloying degree was controlled using various water contents in a solvent. ▶The PtRu alloying degree was changed approximately from 18% to 86%. ▶ Methanol oxidation activity was improved on highly alloyed catalysts. ▶ Stability for methanol oxidation was higher on highly alloyed catalysts.
