PtMo Alloy and MoO x @Pt Core−Shell Nanoparticles as Highly CO-Tolerant Electrocatalysts

PtMo alloy and MoO x @Pt core−shell nanoparticles (NPs) were successfully synthesized by a chemical coreduction and sequential chemical reduction method, respectively. Both the carbon-supported alloy and core−shell NPs show substantially higher CO tolerance, compared to the commercialized E-TEK PtRu...

Zusammenfassung:PtMo alloy and MoO x @Pt core−shell nanoparticles (NPs) were successfully synthesized by a chemical coreduction and sequential chemical reduction method, respectively. Both the carbon-supported alloy and core−shell NPs show substantially higher CO tolerance, compared to the commercialized E-TEK PtRu alloy and Pt catalyst. These novel nanocatalysts can be potentially used as highly CO-tolerant anode electrocatalysts in proton exchange membrane fuel cells.
