Abstract
Low temperature benzene oxidation in the presence of ozone on MnO x/MCM-41 catalysts has been studied. MnO x/MCM-41 catalysts were prepared from two different precursors, Mn(NO 3) 2 and Mn(CH 3COO) 2, and these samples were characterized by N 2 sorption, X-ray diffraction, X-ray photoelectron spectroscopy and temperature programmed reduction. The characterization results showed that the MnO x/MCM-41 prepared from Mn(CH 3COO) 2 had higher oxygen mobility and dispersion than the MnO x/MCM-41 from Mn(NO 3) 2. As a result, the MnO x/MCM-41 obtained from Mn(CH 3COO) 2 showed higher catalytic activity for the oxidation of benzene using ozone; however, without ozone, the catalytic activity was negligible.
