N-Doping Holey Graphene TiO2–Pt Composite as Efficient Electrocatalyst for Methanol Oxidation
Source abstract
Abstract
The nitrogen-doped holey graphene oxide/TiO2 (TiO2–NHGO) composite is synthesized as catalyst support for the Pt catalyst. The resulting catalyst, Pt–TiO2–rNHGO, shows higher activity and stability for methanol electrooxidation than the Pt–rGO, Pt–rHGO, and Pt–rNHGO catalysts. The enhancement is because of the combinatory effect of nanoholes in the graphene plane which provide more active sites and efficient mass transport, well-distributed N-doping, and the uniform distribution of TiO2 NPs on NHGO nanosheets which facilitate to form more uniformly dispersed Pt NPs. In addition, the strong interactions among Pt, TiO2, and NHGO also contribute to enhance the performance of catalyst for methanol oxidation.
