This thesis describes the synthesis process of a mixed oxide with Zn and Zr (ZnxZr1-xOy), through a not yet published technique, as well as the utilization of this material in the acetone synthesis from ethanol. The mean goal was to design a catalyst with enhanced oxy-reduction properties and capability for selfregeneration after each cycle. Monoclinic zirconia (m-ZrO2) is already used in catalysis due to its acidic-basic properties, although its oxy-reduction properties are negligible. The enhancement of the oxy-reduction properties can be reached by substitutional doping of this material with a lower oxidation state metal. The insertion of very small quantities of Zn in the m-ZrO2 lattice, showed a high increment of its reducibility. The mixed oxides obtained were characterized by several techniques and catalytically tested in the acetone synthesis from ethanol. The results showed that doping allows the formation of oxygen vacancies, which allow oxygen mobility and therefore, the enhancement of reducibility. The reaction selectivity had acetone as majority product. It was shown that water is also produced and that it is dissociated in the oxygen vacancies generating oxidant species. The catalysts regeneration occurs due to those oxidant species. Therefore, it was demonstrated that the technique developed in this study was easy and effective in the synthesis of the mixed oxide with Zn and Zr, a catalyst with simple composition able to conduct every step of the acetone synthesis. This is considered the first step in the commercial feasibility of this material.
