▎ 摘　　要

NOVELTY - Platinum-tungsten nitride/reduced graphene oxide (Pt-WN/rGO) catalyst prepared by using tungsten nitride particles and graphene oxide-derived graphene as a catalyst carrier, and supporting platinum metal particles on the carrier by the sodium borohydride reduction method, is claimed. USE - The catalyst is useful for fuel cell anti- carbon monoxide (CO) poisoning (claimed). ADVANTAGE - The catalyst: has sheet structure, synergistic catalytic action between WN and Pt makes the catalyst, excellent HOR performance and stability, and high CO tolerance; and can display excellent CO poisoning resistance in HOR period. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for preparation of platinum-tungsten nitride/reduced graphene oxide catalyst.
