摘要：
The green synthesis of reduced graphene oxide nanoparticles using Nigella sativa seed extract comprises the steps of mixing a quantity of soot or other carbon source in an acid solution while stirring to obtain a solution; adding a first oxidant gradually into the solution to oxidize the soot and obtain a suspension; stirring the suspension while maintaining the temperature of the suspension at about 35° C.; adding Nigella sativa seed extract to the suspension while raising the temperature of the suspension to about 60° C.; adding hydrogen peroxide to the suspension; and isolating the reduced graphene oxide nanoparticles by centrifugation.
