Abstract

This study is aimed at the preparation of mesoporous Cu-Ti-M oxide composites (M=Ce, Zr, Sn) by combination of template assisted hydrothermal technique with the conventional impregnation or novel “chemisorption -hydrolysis” techniques. The obtained materials are characterized by nitrogen physisorption, XRD, SEM, FTIR, HRTEM, XPS, TPR and tested as catalysts for ethyl acetate oxidation, as a probe VOCs molecule. The regulation of the microstructure, surface and redox properties and the related catalytic behavior of the composites by changing of the metal oxide dopant and preparation technique used is discussed in details.
