Abstract: This work presents the results obtained in the characterization and development of gold nanoparticles (AuNPs) immobilized onto two kinds of gel-supported Ionic Liquids (gel-Supported Ionic Liquid like phases, g-SILLPs) and their study as catalysts for the oxidation of organic compounds. The benchmark reaction selected for this purpose was the oxidation of 1-phenylethanol. Besides, the reactions were performed under the concept of the exploitation of enabling techniques using: Microwave heating (as the energy source), water (as the solvent), hydrogen peroxide (as a benign oxidant agent), and supported catalysts (providing a more efficient catalytic processes and easy recovery of the catalyst).
