摘　　要：用一锅水热法制备了颗粒状Pd-Cu双金属催化剂,共同负载于石墨烯上,说明形貌的改变对催化剂的催化性能有很大的影响。相比于商业Pd/C催化剂,颗粒状Pd-Cu/RGO催化剂在碱性条件下的催化活性和稳定性都有所提高,催化活性更加优异。该工作证明了石墨烯负载贵金属是燃料电池催化剂的极好材料,且石墨烯作为碳载体有利于金属的分散,它们相互间也会产生协同效应,进而获得更优异的催化活性。The granular Pd-Cu bimetallic catalyst was prepared by one pot hydrothermal method and co-supported on graphene.Results show that the change of morphology has a great influence on the catalytic performance of the catalyst.Compared with commercial Pd/C catalysts,the catalytic activity and stability of granular Pd-Cu/RGO catalysts are improved under alkaline conditions,and the catalytic activity is more excellent,which has proved that graphene-supported precious metals are excellent materials for fuel cell catalysts,and graphene as a carbon carrier is conducive to the dispersion of metals,and they can also produce synergistic effects on each other,thus obtaining better catalytic activity.
