Title
Highly active Pt–Ru nanowire network catalysts for the methanol oxidation reaction
Abstract

Platinum–ruthenium alloy nanowire networks (Pt–Ru NWNs) have been successfully synthesized by a surfactant assisted soft template strategy, involving the chemical reduction of platinum and ruthenium complexes using sodium borohydride. These materials are investigated as methanol oxidation reaction (MOR) catalysts for fuel cell applications and were found to display exemplary MOR activity and CO tolerance through cyclic voltammetry (CV) testing. Pt–Ru-NWNs investigated in this work are proposed as promising anode replacements to traditional Pt–Ru catalysts in direct methanol fuel cells.
