ABSTRACT

The mesoporous MCM-41 is successfully used as the support to immobilize transition metals like nickel, both in physical and chemical methods. UV-VIS spectroscopy and N₂ adsorption are applied to characterizing these supported catalysts. The results of alcohols oxidation reveal that these supported catalysts have high catalytic activity as their homogenous counterpart does.

Keywords: heterogeneous catalysis, MCM-41, mesoporous, nickel catalyst, oxidation
