摘      要：The properties of γ-ray-reduced graphene oxide samples(GRGOs)were compared with those of hydrazine hydrate-reduced graphene oxide(HRGO).Fourier transform infrared spectroscopy,X-ray diffractometry,Raman spectroscopy,Brunauer-Emmett-Teller surface area analysis,thermogravimetric analysis,electrometry,and cyclic voltammetry were carried out to verify the reduction process,structural changes,and defects of the samples,as well as to measure their thermal,electrical,and electrochemical *** with γ-rays distorted the structure of GRGOs and generated massive defects through the extensive formation of new smaller sp^(2)-hybridized domains compared with those of *** thermal stability of GRGOs was higher than that of HRGO,indicating the highly efficient removal of thermally-labile oxygen species by γ-*** prepared at 80 kGy showed a pseudocapacitive behavior comparable with the electrical double-layer capacitance behavior of ***,the specific capacitance of GRGO was enhanced by nearly three times compared with that of *** results reflect the advantages of radiation reduction in energy storage applications.
