In this study time-efficient size controlled synthesis of stable Pd nanoparticles was carried out using microwave heating method by the decomposition of palladium chloride with glucose in aqueous medium using poly(ethyleneglycol) as capping agent. The benefit of the synthesis is that it was achieved in only 20 s. The synthesized Pd nanoparticles were characterized by UV-Visible spectroscopy, transmission electron microscopy, X-ray diffraction, and particle size analysis. The relative rates of electro-oxidation of formic acid, methanol and ethanol measured by cyclic voltammetry showed that efficiency of Pd nanoparticles as catalyst followed the order: formic acid \ methanol \ ethanol. The current-voltage characteristics improved with increase in either electrolyte (NaOH) or fuel concentrations but decreased with further increase in NaOH concentration.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
