Nanocrystalline Spinel Catalysts for Volatile Organic Compounds Abatement

In the last decade, many efforts have been dedicated to the research of metal oxide catalysts that could be able to replace the noble metals presently used in the catalytic combustion of volatile organic compounds (VOC). Among them, the spinel oxides, such as ferrospinels (AFe2O4), manganites (AMn2O4), and cobaltites (ACo2O4), attracted most interest due to their unique structure and peculiar bulk and surface properties which are expected to have a positive effect on their catalytic behavior in the complete oxidation reaction. Therefore, this chapter focuses on Fe-, Mn-, and Co-based spinel oxides catalysts for the complete oxidation of VOC, with an emphasis on the research published in the last decade. Correlations between the synthesis method used and their physicochemical characteristics, on one hand, and their catalytic performance in VOC total oxidation, on the other hand, are highlighted.
