selective catalytic reduction of nitrogen oxides over Cu-TS-1/cordierite and LaCu-TS-1/cordierite

TS-1 zeolite was successfully synthesized in-situ on a honeycomb cordierite substrate. Cu-TS-1/cordierite and LaCu-TS-1/cordierite were used as catalysts for selective catalytic reduction (SCR) of nitrogen oxides (NOx) in the exhaust of lean burn engine. High catalytic activities were obtained and the main pollutants nitrogen oxides, carbon monoxide and hydrocarbons in the exhaust could be purified together.
