Synthesis of W-modified CeO₂/ZrO₂ catalysts for selective catalytic reduction of NO with NH₃.

ABSTRACT: In this paper, a series of tungsten-zirconium mixed binary oxides (denoted as W _m ZrO _x ) were synthesized via co-precipitation as supports to prepare Ce_0.4/W _m ZrO _x catalysts through an impregnation method. The promoting effect of W doping in ZrO₂ on selective catalytic reduction (SCR) performance of Ce_0.4/ZrO₂ catalysts was investigated. The results demonstrated that addition of W in ZrO₂ could remarkably enhance the catalytic performance of Ce_0.4/ZrO₂ catalysts in a broad temperature range. Especially when the W/Zr molar ratio was 0.1, the Ce_0.4/W_0.1ZrO _x catalyst exhibited the widest active t
