Abstract: 
(DIV) Ceria (CeO2) catalysts have been a useful solid phase catalyst that has seen an increase in industrial use recently due to its convenient and tunable redox activity. The Ce+3/Ce+4 catalytic cycle readily available on the surface of the substrate allows for facile oxygenation of several important organic substrates. Further alterations of ceria allows for more complex catalytic systems and specific tailorability. ISURF researchers achieve this tailorability by incorporating surface phosphates onto Ceria. Incorporation of the phosphate substrates increases the Brønsted acidity and upon deposition of Pd, the material showed activity for eugenol hydrogenation and hydrogenolysis, propylene oxide hydrolysis, and indigo carmine photo degradation.
Benefits:
