摘要: Abstract A facile solid-state synthetic route was used to fabricate graphene oxide (GO) decorated with Ag nanoparticles. Ag/GO nanocomposites were prepared by reducing silver acetate ascorbic acid in the presence of GO at ambient conditions. The characterization results showed that nanoparticles an average diameter ~ 50 nm well dispersed on surface nanosheets. Moreover, application obtained as a catalyst reduction 4-nitrophenol (4-NP) 4-aminophenol NaBH 4 demonstrated. exhibited high activity and stability for catalytic 4-NP.
