Oxidation of alcohols to their corresponding carbonyl compounds is one of the most important functional groups transformations in organic chemistry. The development of an environmentally and economically process by H2O2 as oxidant along with recyclability of the catalyst is a challenge [1]. Heteropoly acids (HPAs) possess interesting properties that make them useful for catalytic applications [2]. HPAs have the low surface area in nonpolar solvents and are soluble in polar solvents that reduce their recyclability [3]. Therefore, we were planning heterogenization of tungstophosphoric acid via immbilization on graphene oxide/Fe3O4 nanocomposite (GO/Fe3O4/HPW) that has high surface area, high stability and separability.
