Abstract: A series of bismuth incorporated MCM-41 mesoporous samples were synthesized and characterized by inductive coupled plasma emission spectrometer (ICP), X-ray diffraction, N2 adsorption/desorption, transmission electron microscopy, and UV-Vis spectroscopy. These samples catalyzed the selective oxidation of 4-chlorotoluene efficiently even on a large scale with H2O2 as oxidant in acetonitrile. No bismuth was detected by ICP in the condensed reaction mother liquid, and the recycle test proved the catalyst was stable.

Key words: Bi-MCM-41, 4-chlorotoluene, oxidation, 4-chlorobenzaldehyde
