“…A superior Ce-W-Ti oxide catalyst was prepared by doping W into the Ce-Ti oxide catalyst [53]. The Ce-W-Ti oxide catalyst showed both enhanced low-temperature activity and hightemperature activity simultaneously, combined with enhanced N2 selectivity, compared with the undoped Ce-Ti oxide catalyst.…”

The selective catalytic reduction of NOx with NH3 (NH3-SCR) is one of the widely used NOx control strategies for stationary sources (particularly for power plants) and mobile sources (particularly for diesel vehicles). The application is aimed at meeting the increasingly stringent standards for NOx emissions. Recently, ceria has attracted much attention for its applications in NH3-SCR catalysts owing to its unique redox, oxygen storage, and acid-base properties. In this article, we comprehensively review recent studies on ceria for NH3-SCR catalysts when used as support, promoter, or the main active component. In addition, the general development of ceria for NH3-SCR catalysts is discussed.

“…Commercially, NH3 is generated in situ by urea decomposition and the BlueTec system developed by Mercedes Benz uses a 32.5% urea solution for NH3 generation. The best SCR catalysts are zeolites exchanged with different metals as Fe or Cu [33,34], although oxides as CeO2-TiO2 or Ce-W-Ti mixed oxides have also been tested [35,36].…”

“…Metal oxides (La, Ce, and Zr) were prepared by a homogeneous precipitation method with the corresponding metal nitrate as precursor and urea as the precipitant [43]. The precipitates were dried in an oven at 373 K overnight and were then calcined at 873 K for 5 h in air.…”
