In this investigation, GO-ZnO nanocomposites were synthesized by using hydrothermal method. The structure, morphology and optical properties of synthesized nanocomposites were analyzed through Fourier transformed infrared spectroscopy (FTIR), X-ray diffraction (XRD), Scanning electronic microscopy (SEM), and UV-Visible spectroscopy. The XRD pattern confirmed the formation of Graphene decorated with hexagonal ZnO with high crystallinity. SEM revealed that the graphene paternity image decorated ZnO uniformly. UV-Visible spectroscopy was utilized to study photocatalytic degradation of synthesized materials against rhodamine B and methyl blue dyes and good catalytic activity was observed for both samples. Graphene-ZnO nanocomposites showed higher catalytic activity than ZnO nanoparticles.
Rather than regarding endogenous Fe in coal gasification slag (CGS) as a waste, it could instead be considered as a potential source to develop an efficient catalyst for energy conversion...
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
