Abstract
In this work, novel Cu–Co bimetal/reduce graphene oxide nanostructures with excellent catalytic activity were prepared by embedding Cu–Co bimetallic nanospheres into the interlayer of graphene. The composite materials were characterised by X-ray diffraction (XRD), Fourier transform infrared (FTIR), and scanning electron microscopy (SEM) etc. The characterisation results indicated that the diameters of the bimetallic nanospheres were controlled within ∼60 nm, which embedded uniformly in graphene. A series of electrochemical tests were carried out and the composites were found to exhibit excellent oxygen evolution properties under alkaline conditions. The excellent catalytic activity and stability make the composite have great potential for wide application and provide a basis for its industrial application.
