Promotional mechanism of enhanced denitration activity with Cu modification in a Ce/TiO 2 -ZrO 2 catalyst for a low temperature NH 3 -SCR system

This study aims to investigate the enhanced low temperature denitration activity and promotional mechanism of a cerium-based catalyst through copper modification. In this paper, copper and cerium oxides were supported on TiO -ZrO by an impregnation method, their catalytic activity tests of selective catalytic reduction (SCR) of NO with NH were carried out and their physicochemical properties were characterized. The CuCe/TiO -ZrO catalyst shows obviously enhanced NH -SCR activity at low temperature (
