Abstract:A simple photodeposition method was presented for synthesis of novel Ag/g-C<inf>3</inf>N<inf>4</inf>composite nanosheets (AGCNs) where Ag nanoparticles with diameters of 5 to 20 nm were evenly loaded onto g-C<inf>3</inf>N<inf>4</inf>nanosheets forming a heterogeneous structure. Compared to the pure g-C<inf>3</inf>N<inf>4</inf>nanosheets, more intensive absorption within the visible light range and lower recombination probability of photogenerated charge carriers were observed in AGCNs. Photocatalytic activities of the as-prepared samples were evaluated by the photocatalytic oxidation decomposition of Rhodamine B (RhB) under visible light irradiation. The experimental results showed that AGCNs (8 wt%) exhibited the highest photocatalytic activity and the corresponding degradation rate was 7 times as much as that of pure g-C<inf>3</inf>N<inf>4</inf>nanosheets.<br/> © 2015 Elsevier B.V.
