dc.description.abstract | ABSTRACT newlineNoble metal nanoparticles have an awfully surface-to-volume ratio and high stability of newlineatoms at their surfaces and are known to exhibit high catalytic performance in a variety of preparative chemical transformations. These emergent properties have the potential for great impacts in optical, electronics, mechanical, biomedical, catalysis and other fields. The traditional synthetic methodologies for producing of nobel metal nanoparticles involve various physical or chemical methods with the aid of toxic and hazardous reducing and stabilizing agents. Microwave assisted green synthesis method save energy and are environmentally friendly, because the reactions take place in closed isolated system conditions. In the present study nobel metal naoanoparticles i.e. Pd, Ag, Pt and Au synthesized using gums such as guar gum, neem gum, gum acacia and gum ghatti in a microwave oven. newlinePalladium nanoparticles are one of the most vital and interesting nanomaterials among several metallic nanoparticles that are involved in catalytic, sensor design, coatings, polymer membrane, fuel cells and biomedical applications. In present study we synthesized PdNPs stabilized in GG using GG as reducing and stabilizing agent by microwave technique.Evidence for the interaction of hydroxyl groups in the reduction and stabilization of the PdNPs was obtained from the FTIR spectra of GG and microwave assisted green synthesized PdNPGG. Further studies were carried out using X-ray diffraction measurements to confirm the crystalline nature the PdNPGG. It is also cleared from the TEM image that the palladium nanoparticles are spherical and highly dispersed and there is no aggregation of them. The catalytic properties of microwave assisted PdNPGG was tested for reduction of 4-NP in water. The antioxidant activity of PdNPGG examined by comparing the percentage quenching of DPPH radicals with that comparison of AA. | |
