摘要：
The green synthesis of a reduced graphene oxide (rGO) silica (SiO2) nanocomposite using Nigella sativa seed extract includes mixing a quantity of carbon source in an acid solution while stirring to obtain a solution adding a first oxidant gradually into said solution to oxidize the soot and obtain a first suspension stirring the first suspension while maintaining a temperature of said suspension to about 35° C. adding plant seeds extract to the first suspension while raising the temperature of the suspension to about 60° C. adding a second oxidant to said suspension to form the reduced graphene oxide nanoparticles isolating the reduced graphene oxide nanoparticles by centrifugation suspending the reduced graphene oxide nanoparticles in water adding a solution comprising tetraethyl orthosilicate (TEOS), concentrated aqueous ammonia solution and a plant seeds extract under ultrasonication and increasing the temperature to about 90° C. to form reduced graphene oxide-silicon dioxide nanocomposite suspension.
