Abstract

Abstract : A Pt0.3ML /Ir(111) model catalyst showed desirable properties for a polymer electrolyte fuel cell anode, including enhanced hydrogen oxidation activity and suppressed H2 O2 generation. Abstract : Simultaneous accomplishment of high hydrogen oxidation reaction (HOR) activity and suppressed hydrogen peroxide (H2 O2 ) generation is desired for anode catalysts of polymer electrolyte fuel cells. 0.3 monolayer-thick-Pt-deposited Ir(111) showed three-fold higher HOR activity than Pt(111) and suppressed H2 O2 generation under the detection limit, providing insights for effective catalyst development.
