The Emergence of the Ubiquity of Cerium in Heterogeneous Oxidation Catalysis Science and Technology

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