|Abstract: ||Transition metal nanoparticles (MNPs) have attracted increasing attention because of their well defined large surface area, stability, and surface permeability and their potential applications in a number of areas including using as efficient catalysts in organic reactions, optoelectronic devices, sensors, drug-delivery carriers, energy-storage devices, chemical/ biological separation and sensing.Although a growing number of applications have appeared lately for MNPs, the catalytic application of such MNPs in different organic reactions has just begun to unfold. The advantages associated with supported catalyst are the catalyst is easily and safely handled compared to the particles in the colloidal phase and metal catalyst immobilized on a support could be easily separated from the product and effectively reused etc.Among different support materials, metal oxides in nanometer dimension such as SiO2, ZnO, FexOy, Al2O3, TiO2 or MgO are widely exploited to carry MNPs as they offer high thermal and chemical stabilities combined with a well developedstructure and high surface areas, meeting the requirement of applications in catalysis. Also metal oxide nanoparticles are considered to be non toxic and hence are environmentally friendly. The different reactions catalysed by MNPs includeepoxidation of alkene, oxidation of alcohol,allylic oxidation, CO oxidation, C C coupling reactionand hydrogenation.Considering the recent developments in the field of catalysis, the current focus of our research work is to design a metal oxide supported MNPs system by simple chemical approach involving greener approach. In addition, a major focus will be given to the study of catalytic behavior of these supported MNPs towards various organic reactions.The main objectives are-
newlinei. To design a methodology by which a diverse range of metal oxide NPs such as ZnO, ZrO2, SnO2, MgO, SiO2 etc. can be synthesized.
newlineii. Incorporation of MNPs such as Pd, Ag, Au, Co, Ni etc. into the synthesized metal oxide nanoparticles by different wet chemistr|
