Paperback. Etat : new. Paperback. Noble metal nanoparticles have an awfully surface-to-volume ratio and high stability of atoms 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.

Paperback. Etat : new. Paperback. Les nanoparticules de metaux nobles ont unrapport surface-volume impressionnantet une grande stabilite des atomes a leur surface. Elles sont connues pour leurs performances catalytiques elevees dans une variete de transformations chimiques preparatoires. Ces proprietes emergentes peuvent avoir un impact considerable dans les domaines de l 'optique, de l'electronique, de la mecanique, de la biomedecine, de la catalyse et d'autres encore. Les methodologies synthetiques traditionnelles pour la production de nanoparticules de metaux nobles impliquent diverses methodes physiques ou chimiques a l'aide d'agents reducteurs et stabilisateurs toxiques et dangereux. La methode de synthese verte assistee par micro-ondes permet d'economiser de l'energie et est respectueuse de l'environnement, car les reactions ont lieu dans des conditions de systeme isole ferme. Dans la presente etude, des nanoparticules de metaux nobles (Pd, Ag, Pt et Au) ont ete synthetisees a l'aide de gommes telles que la gomme de guar, la gomme de margousier, la gomme d'acacia et la gomme ghatti dans un four a micro-ondes.
