| Abstract: | Ag2S/rGO nanocomposites were synthesized in situ on the surface of GO using a gram-negative bacterium (S. oneidensis MR-1) as a biological reducing agent and Na2S2O3 as an electron acceptor.The results showed that Ag2S nanoparticles with a particle size of about 10 nm were uniformly distributed on reduced graphene oxide (rGO) surface.The photoelectric performance test showed that the photoelectric current density of the Ag2S/rGO nanocomposites was about 3 times higher than that of the pure Ag2S. The separation efficiency of the photoelectron-hole pair was higher than that of Ag2S, and its photoelectric chemical performance was more excellent. |
