“…In addition to formaldehyde and CO oxidation, cerium oxide as a catalyst and/or catalyst support has been reported to be beneficial in the total oxidation of a wide range of other VOC hazardous pollutants, including chlorohydrocarbons [97], ethylene oxide, peroxides, propane [98], acetaldehyde, acrolein, aromatic hydrocarbons [99] including by photooxidation [100], acrylonitrile [101,102], HCN [103], and soot/particulates from diesel engine exhaust. Preparation methods also have a significant impact on ceria-supported Pt for VOC oxidation with the use of a metal-organic framework (MOF) as a precursor material in the synthesis resulting in a Pt/CeO 2 catalyst with enhanced Pt dispersion and higher turnover frequencies for toluene oxidation [104].…”

Research into the incorporation of cerium into a diverse range of catalyst systems for a wide spectrum of process chemistries has expanded rapidly. This has been evidenced since about 1980 in the increasing number of both scientific research journals and patent publications that address the application of cerium as a component of a multi-metal oxide system and as a support material for metal catalysts. This review chronicles both the applied and fundamental research into cerium-containing oxide catalysts where cerium’s redox activity confers enhanced and new catalytic functionality. Application areas of cerium-containing catalysts include selective oxidation, combustion, NOx remediation, and the production of sustainable chemicals and materials via bio-based feedstocks, among others. The newfound interest in cerium-containing catalysts stems from the benefits achieved by cerium’s inclusion, which include selectivity, activity, and stability. These benefits arise because of cerium’s unique combination of chemical and thermal stability, its redox active properties, its ability to stabilize defect structures in multicomponent oxides, and its propensity to stabilize catalytically optimal oxidation states of other multivalent elements. This review surveys the origins and some of the current directions in the research and application of cerium oxide-based catalysts.
