Abstract
A novel graphene oxide-Ag-C6H5Ag3O7 nanocomposite was prepared by a facile precipitation reaction with the aid of photo-reduction. The rich surface functional groups of graphene oxide (GO) interacted with silver cations, provided the nucleation sites and induced the formation of C6H5Ag3O7 nanoparticles on the GO surface uniformly. The nanocomposite displayed an enhanced photocatalytic activity compared with pure C6H5Ag3O7 and GO under simulated sunlight, due to the reduced recombination of plasmon-induced electron–hole pairs on the Ag nanoparticles by the GO. This study likely provides one possibility of exploiting stable Ag/silver (I) complex photocatalysts in dealing with environmental contaminants.
