Selective catalytic reduction of no with ammonia on titania pillared clays |
초록 |
TiO2-pillared clays were synthesized by pillaring TiO2 onto the pure bentonite. As the pillaring agent was used a solution of partially hydrolyzed Ti-polycation which had been prepared by adding TiCl4 into HCl solution. Successful intercalation of TiO2 could be achieved, and the physical properties such as d001 spacing. The N2 adsorption isotherms showed the presence of both the micropores and mesopores in the pillared clays. TPD and FTIR analyses showed the wide presence of the Brønsted acid site which is essential to the SCR of NO with NH3. When Fe2O3 was incorporated into the TiO2-PILCs, the Brønsted acidity increased significantly, and even the complete conversion of NO could be achieved with the Fe2O3/TiO2-PILCs at the temperature window between 375-400℃. |
