Facile one-pot solvothermal technique to synthesis ZnS / graphene nanoplatelets (0.2) nanocomposites

Abstract

Abstract In this work, we report the fabrication of ZnS / graphene nanoplatelets (0.2) nanocomposites (ZnS/G(0.2)) by a simple step solvothermal manner. The nanocomposite with weight ratio (0.2) of graphene nanoplatelets was prepared and characterized by several techniques. X-Ray diffraction measurements have shown three sharp peaks at (111) ‘(220) ‘(311) Miller indices, which referred to Sphalerite and Wurtzite phases of the cubic face. The average crystal sizes of 11.03 nm to 14.41 nm for ZnS nanoparticles. The graphene nanoplatelets enhanced crystallinity properties of prepared nanocomposites. Fourier-transform infrared and Raman spectrums confirm formation of ZnS nanoparticles and ZnS/G(0.2) nanocomposites. Furthermore, FESEM was performed to study morphology and structure of nanocomposites. BET isotherm, and the BJH method have given information consistent with Type V with the H3 hysteresis loops. Moreover, the results have supported the effective change in the surface area, pore-volume, pore diameter, and external surface area values.
