Synthesis of palladium nanoparticles (PdNPs) employing green reagents like glucose and starch was performed in two different reaction configurations: (i) the conventional batch method and (ii) with continuous microreactor technology. The synthetized nanoparticles were characterized by XRD, UV-vis spectroscopy and TEM. The reaction conducted in the microreactor led onto smaller PdNPs with a monodispersed size distribution. The catalytic response of both obtained materials was tested on the reduction of 4-nitrophenol. As a result, the smaller PdNPs synthesized with the continuous flow presented higher catalytic activity due to the high catalytic surface area of the small nanoparticles.
