| Abstract: | Niobium acid has been doped in MCM-41 for the synthesis of novel efficient Nb 2O 5/MCM-41 catalyst by using aqueous Nb-oxalic acid compounds as the precursor. The catalyst has been characterized by means of XRD, BET, N 2-adsorption and desorption methods and shows a satisfying catalytic performance in the selective oxidation of cyclopentene to glutaraldehyde. The conversion reaches 100% and the yield has come up to 50%, suggesting its favorable application potential in industry. |
