Abstract: Here we present the results obtained in the development of Au nanoparticles (AuNPs) immobilized on a gel-supported Ionic Liquid (gel-Supported Ionic Liquid like phase, g-SILLP) and their study as catalysts for the oxidation of alcohols. The benchmark reaction selected for this purpose was the 1-phenylethanol oxidation. Besides, the reactions were performed under benign conditions using: Water(as the solvent and reaction medium), hydrogen peroxide (as the benign oxidant agent), microwave irradiation (as the heating source) and supported catalyst (providing a more efficient catalytic process).
