Abstract
Ce/TiO2 is a prospective catalyst used for low temperature selective catalytic reduction (SCR) of NO with NH3. In this paper, the poisoning effect of Zn and Pb on the SCR performance of Ce/TiO2 catalyst was investigated. Experimental results indicated that both Zn and Pb had a poisoning effect on Ce/TiO2 catalyst, and Pb exhibited more poisoning effect than Zn in most of the reaction temperature range. Combined with the characterization results, we proposed that the enlargement of TiO2 nanoparticles, the reduced chemisorbed oxygen content and surface acidity all contribute to the deactivation of Zn–Ce/TiO2 and Pb–Ce/TiO2.
