Abstract: Photoreduction of graphene oxide, by UV-generated ketyl radicals, to graphene. The photoreduction is versatile and can be carried out in solution, solid-state, and even in polymer composites. Reduction of graphene oxide can take place in various polymer matrixes. Methods for producing graphene-supported metal nanoparticles by photoreduction. Graphene oxide and a metal nanoparticle precursor are simultaneously reduced by the action of photogenerated ketyl radicals. Photoreduction is performed on polymer composite films in one embodiment.
