Graphene/SnO₂/Citric Acid Nanocomposites as the Excellent Sorbent for Removal of Crystal Violet and Methylene Blue

Abstract:

A simple, fast one-step method was used to prepare graphene/SnO₂/citric acid (GN/SnO₂/CA) nanocomposites. Fourier transform Infrared spectroscopy, UV-vis adsorption spectroscopy, transmission electron microscopy, X-Ray diffraction, Raman spectroscopy and X-ray photoelectron spectroscopy were employed to characterize as-prepared GN/SnO₂/CA nanocomposites. Furthermore, in the adsorption performance research, GN/SnO₂/CA nanocomposites indeed displayed excellent adsorption ability towards cationic dyes.
