Abstract:This study reports a strategy for synthesis of V4+-doped and graphene-decorated V2O2/biomass carbon nanocomposite using graphene quantum dot. The introduction of graphene quantum dots and cotton significantly improves the supercapacitor performance.
Low luminous efficiency at visible light excitation restricts many applications of graphene quantum dot in bioanalysis, bioimaging and light-emitting diode. The paper reports synthesis of folic acid, histidine and serine-functionalized...
