Ceria-supported metal catalysts

Supported noble-metal catalysts are still regarded as the most active systems for oxidation reactions when compared to transition-metal oxides, despite being more expensive and more sensitive to poisoning. A definite target of research in this field is the development of active catalysts using a combination of transition-metal oxides with the smallest possible amount of a precious metal. 

As shown from the literature results mentioned above, despite the significant progress in the development of catalysts for the total oxidation of organic molecule, it is actually very difficult to design a system that works efficiently as a general VOC combustion catalyst. The variety of molecules in a real feed requires specific catalysts for different groups of compounds, such as aliphatic, aromatic, and chlorinated.
