Mesoporous Pt and Pt/Ru alloy electrocatalysts for methanol oxidation

▶ Mesoporous Pt and Pt/Ru catalysts with 2D-hexagonal mesostructure were synthesized using a Pluronic F127 ® template. ▶ Large electrochemical surface areas were observed for the catalysts prepared at high overpotentials. ▶ The Pt/Ru alloy (3 at% Ru) exhibited more than three times the limit mass ac...
