Liquid-Phase Catalytic Oxidations with Perovskites and Related Mixed Oxides

Liquid-Phase Catalytic Oxidations with Perovskites and Related Mixed Oxides 

Oxidation is one of the most important reactions in industrial organic synthesis [1-3] and can be carried out in both gas [4] and liquid [5,6] phases. Catalytic oxidation reactions in liquid phase were achieved in conditions of catalytic [5], photocatalytic [7], electrocatalytic [8], and photoelectrocatalytic [9] processes. At the same time, the new developments in the synthesis of materials led to the discovery of a large variety of catalysts and applications, including new catalysts for the liquid-phase oxidation reactions. A special interest in this sense was addressed to green and sustainable sources of oxidation [10].

The selection of an efiicient catalyst and the choice of the reaction conditions are the key steps to realize an ideal oxidation procedure. Many of the heterogeneous catalysts used in liquid-phase oxidation are mixed oxides with one or more transition metak. For these catalysts, the active site is directly involved in successive redox cycles, which underlines the fundamental role of the electronic fiic-tor [30]. Transition metal oxides also exhibit surface acid-base properties. Many authors have attempted to relate these properties with the activity or selectivity in oxidation reactions [31] and photo-oxidative degradation of organic compounds.
