    AnnotationMesoporous ceria-titania binary materials were used as a host matrix of nanosized copper oxide species. The obtained materials were characterized by XRD, nitrogen physisorption, UV-Vis, Raman, FTIR and temperature-programmed reduction with hydrogen. Their catalytic activity was tested in total oxidation of ethyl acetate and methanol decomposition to CO and hydrogen with a potential application in VOCs elimination and alternative fuels, respectively. The variations in the ceria-titania support composition affected the dispersion and the oxidative state of loaded copper species. The facilitated electron transfer between the copper species and ceria-titania support improved the catalytic activity in both catalytic processes and this effect could be successfully controlled by the Ti/Ce ratio in the samples.
