Synthesis and characterization of graphene oxide coated silica nanoparticles

Abstract

Graphene oxide (GO) is capable of absorbing many common pollutants of water such as heavy metals and organic contaminants. However, graphene oxide membranes easily disintegrate in water and aggregates. T his decreases its adsorption capacity and diminishes its practical applications. Therefore, to prevent the above problems graphene oxide is combined with silica nanoparticles.
