The utilization of ceria in industrial catalysis

The main applications of cerium dioxide in industrial catalysis are reviewe d, with particular attention to the role played by ceria. The main uses of CeO2 are connected to depollution of noxious compounds from gaseous streams originating from industrial productions and from automobiles (de-SOx in FC C processes; treatment of emissions from spark-ignited and diesel engines), although ceria is also a key component of catalyst formulation for the deh ydrogenation of ethylbenzene to styrene. Recent advances in the application of ceria for the removal of organic compound from wastewater through oxida tion (catalytic wet oxidation CWO) are also reviewed. (C) 1999 Elsevier Sci ence B.V.
