Description:
An environmentally friendly one-step method to synthesize palladium (Pd) nanobelts, nanoplates and nanotrees using vitamin B1 without using any special capping agents at room temperature is described. This greener method, which uses water as benign solvent and vitamin B1 as a reducing agent, can be extended to prepare other noble nanomaterials such as gold (Au) and platinum (Pt). The synthesized self-assembled Pd nanoparticles were characterized using, scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray diffraction (XRD) and UV spectroscopy. The Pd nanoparticles showed excellent catalytic activity for several C-C-bond forming reactions such as Suzuki, Heck and Sonogashira reactions under microwave (MW) irradiation conditions.
