摘要: Abstract In the present study, graphene nanosheets are synthesized using sunlight irradiation focussed onto graphite oxide. The morphological characteristics of examined Scanning Electron Microscopy (SEM) and Transmission (TEM). Raman spectroscopy X-ray diffraction (XRD) used for structural characterization sample. electrochemical performance is evaluated cyclic voltammetry (CV), charge-discharge impedance spectroscopy. A high specific capacitance value 223 F g −1 obtained voltammetry. detection H 2 O 2, a common biological species solar demonstrated. CV to study electrocatalytic activity material. High sensitivity 64.79 μA mM cm −2 reported.
