Abstract
MCM-41 incorporated with 10 % copper and iron was synthesized via sol—gel technique at room temperature. The catalysts were labelled as Cu-10 and Fe-10 respectively. Rice husk ash (RHA) was used as the silica source. In this research, the catalysts were characterized by using FTIR, XRD, Nitrogen sorption analysis, TEM, SEM and pyridine adsorption test. From the characterization analysis, the results showed that the MCM-41 framework was maintained depending on the percentage loading of copper and iron. In addition, the results indicated that MCM-41 materials with a hexagonal array of uni-directional pores could be synthesized successfully at room temperature in the presence of copper and iron. Cu-10 and Fe-10 catalysts have been tested in the oxidation of benzyl alcohol with hydrogen peroxide as oxidant. Iron incorporated MCM-41 gives higher catalytic activity compared to other catalyst with 67 % conversion of benzyl alcohol and 85 % selectivity to benzaldehyde.
