Graphene/NiS2 composite was obtained through a template-free solvothermal reaction using graphene oxide (GO), Na2S2O3·5H2O and NiCl2·6H2O as reactants. Na2S2O3·5H2O plays an important role as the reducing agent for GO as well as the sulfur source for NiS2. Electrochemical behaviour of the graphene/NiS2 composite was studied through cyclic voltammetry and galvanostatic charge-discharge. As for the...
Nanohybrid of Zinc tungstate (ZnWO 4 ) nanoparticles and chemically reduced graphene oxide (RGO) sheets was synthesized with a “green”, ionic-liquid assisted hydrothermal process. The prepared RGO–ZnWO 4 s have been thoroughly characterized by spectroscopic and thermogravimetric analysis. Based on transmission electron microscopic study, RGO does not change the structure and morphology...
