A novel ceria–activated carbon composite for the catalytic ozonation of carboxylic acids

Mineralization of Substituted Aromatic Compounds by Ozonation Catalyzed by Cerium Oxide and a Cerium Oxide-activated Carbon Composite

“…In a previous work [8], we prepared a cerium oxide/ activated carbon composite for the application in catalytic ozonation reactions. The results obtained showed that cerium oxide catalysts are effective ozonation catalysts for the removal of carboxylic acids (oxalic and oxamic acids).…”

“…The application of cerium-based catalysts in several processes, including wet air oxidation reactions [5,6], has been extensively studied. However, only a few studies have reported the use of cerium-containing catalysts for the ozonation of organic compounds [7,8].…”

Selective catalytic reduction of nitric oxide over cerium-doped activated carbons

“…In inert atmosphere, major amounts of Ce(NO 3 ) 3 precursor decomposed into CeO 2 (Ce(IV)). However, it also forms Ce(III) due to the transfer of electrons from the surface of activated carbon to the metal oxide (Faria et al, 2008). Tang et al (2009) studied the characterization and catalytic activity of manganese oxide supported on activated 21 carbon.…”

Cerium incorporated MCM-48 (Ce-MCM-48) as a catalyst to inhibit bromate formation during ozonation of bromide-containing water: Efficacy and mechanism

“…According to Faria et al (2008), the Ce3d spectrum can be deconvoluted to 10 peaks, that is, 6 for Ce(IV) and 4 for Ce(III). The measured and fitted Ce3d XPS spectra indicated the presence of mixed valence states of Ce (III and IV) on the catalyst surface (Fig.…”
