Preparation of Three-Dimensional Graphene/Bimetallic PtPd Nanoparticle Hybrid and Its Electrocatalysts Application for H2O2

Abstract

Abstract-a hybrid material of three-dimensional graphene sheets beaded with bimetallic PtPd nanoparticle was prepared by using a simple process. The three-dimensional graphene/PtPd hybrids exhibited an interconnected microporous framework with PtPd NPs dispersed and encapsulated within the graphene sheet layers. In addition, the three-dimensional graphene/PtPd hybrids show a highly sensitive response to H 2 O 2 reduction and oxidation.
