Abstract

A single step synthesis of gold nanoparticles (AuNPs) and their deposition on a graphene oxide (GO) sheets in a microflow reactor was investigated. Gold nanoparticles were synthesized by chemical reduction in aqueous solution using dimethylamina borane (DMAB) as reductant. The influence of pH, initial concentration of gold(III) salt and flow rate was studied. The results demonstrate that microflow reactor is suitable for a single step synthesis and deposition of AuNPs. Size and size distribution depends on the flow rate and pH of the solution.
