Abstract
The ZnSe-rGO nanocomposite with various stacking of rGO by simple solvothermal route was reported along with its characterization through X-ray diffraction (XRD), scanning electron microscopy (SEM), high resolution transmission electron microscopy (HRTEM), Raman and photoluminescence spectroscopy. SEM as well as TEM pictures predict that ZnSe nanoparticles were embedded on the graphene sheets with average particle size 15 nm and are well decorated on the surface of rGO sheets. Photocatalytic activity's improvement for degradation of MB by ZnSe-rGO nanocomposites was observed, which is described in term of interaction between ZnSe nanoparticles and rGO sheets and charge carrier sepatation. It is also reflected in photoluminescence and Raman studies. This plays a crucial role in minimizing electron-hole recombination through transfer of electron from ZnSe to rGO.
