Abstract Ag/graphene nanocomposites have been demonstrated to be promising catalysts for hydrogenation reduction of p ‐nitrophenol ( p ‐NP) to p ‐aminophenol ( p ‐AP). Herein, we reported the synthesis of graphene‐supported silver nanoparticles (Ag/G) using one‐step and stabilizer‐free process. The obtained Ag/G nanocomposites were demonstrated to be efficient catalysts for the reduction of p ‐NP to p ‐AP. The reaction kinetics of the catalytic reduction, including the effects of catalyst concentrations and temperatures are reported. These results are of significant values for the scale‐up of using Ag/graphene catalysts for hydrogenation reduction.
