Abstract

Graphene nanosheets loaded with highly dispersed platinum nanoparticles (Pt@GNSs) are prepared by a simple and effective hydrothermal method. The Pt@GNS as an air cathode material exhibits a very high initial discharge capacity of 7574 mA h^-1 g^-1 at a current density of 0.1 mA cm^-2 and delivers a stable cycling performance. The electrocatalytic characteristics of Pt on the Na-O₂ cell have been investigated for the first time.
