Resumo
A commercial niobium oxide was used to form a gelled material, which was lyophilized producing a novel
polyoxoniobate catalyst (L-AmNbO) containing peroxo groups. The activity of this new catalyst was assessed
through oxidation reactions of the cyclohexene. In the presence of L-AmNbO catalyst, the oxidation of cyclohexene with H2O2 reached 90% of conversion after 12 h at 75 ◦C, with selectivity for 1,2-cyclohexanediol (~
50%). The catalytic results and the surface properties of this new material indicated that it can be a promising
catalyst for niobium compounds applications in the selective oxidation of cyclohexene.
