Synthesis in a flow microreactors has become very promising field of chemistry. Using such devices it is possible to conduct highly exothermic reactions, accelerate slow reactions by very fast mixing of reagents, carry reactions in a high temperature and pressure, etc. It is very interesting to see if these reactors can be used for synthesis of monodispersive metallic nanoparticles.
Abstract: The aim of this study was to produce gold nanoparticles by reduction of gold (III)chloride complex ions ([AuCl4]) with sodium borohydride (NaBH4) in the presence of polyvinyl alcohol (PVA) as a stabilizer. The influence of temperature and the flow rate on the size and distribution of obtained nanoparticles were studied.
