Highly active Pt\u2013Ru nanowire network catalysts for the methanol oxidation reaction

Platinum\u2013ruthenium alloy nanowire networks (Pt\u2013Ru 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\u2013Ru-NWNs investigated in this work are proposed as promising anode replacements to traditional Pt\u2013Ru catalysts in direct methanol fuel cells.Peer reviewed: YesNRC publication: Ye
