Metal oxide catalysts are much more complicated than metal catalysts. The reason is that the cations of the metal atoms could exhibit a few different oxidation states on surface of the same catalyst particle or change of their oxidation states under different reactive environments. The complication of surface chemistry and structure of a metal oxide makes studies of surface of an oxide catalyst very challenging.
The present article contains the fundamentals of heterogeneous catalysis and a description of the main domains of heterogeneous catalysis in metal oxide and mixed metal oxide catalysts and also considers current and prospective major applications, where recent advances in the science of metal oxide catalysts have major economic and environmental impacts.
Metal oxides are utilized both for their acid–base and redox properties and constitute the largest family of catalysts in heterogeneous catalysis. A variety of metal oxide and mixed metal oxides (MMOs), containing alkali, alkaline, rare earth and noble metals, and their applications are presented.
Keywords: metal oxide catalysts; mixed metal oxide catalyst, heterogeneous catalysis
