Preparation, Characterization and Catalytic Performance of Ti-Co-SBA-15 Catalysts

A series of Ti-SBA-15 with different titanium loadings were synthesized under conventional hydrothermal conditions, using tetra-n-butyl titanate as the titanium source. The Ti-Co-SBA-15 catalysts were synthesized by using the impregnation method. The catalyst samples were characterized using XRD, UV-Raman, FTIR, low temperature N-2 adsorption-desorption. The catalytic performance of the catalysts was evaluated for oxidation of 4-tert-butyltoluene into 4-tert-butylbenzaldehyde under mild conditions. The results show that the prepared catalysts have larger surface area and pore size, and they contain four coordinated titanium and cobalt. The catalysts have higher activity, selectivity and yield of 4-tert-butylbenzaldehyde in the oxidation reaction of 4-tert-butyltoluene.
