Abstract

In this studyNO reduction behaviors of copper-loaded mesoporous molecular sieves (Cu/MCM-41) have been investigated. The Cu loading on MCM-41 surfaces was accomplished by a chemical reduction method with different Cu contents (5,10,20,and 40%). N2/77 K adsorption isotherm characteristics,including the specific surface area and pore volume,were studied by BET's equation. NO reduction behaviors were confirmed by a gas chromatography. From the experimental results,the Cu loading amount on MCM-41 led to the increase of NO reduction efficiency in spite of decreasing the specific surface area of catalysts. This result indicates that highly ordered porous structure in the MCM-41 and the presence of active metal particles lead the synergistical NO reduction reactions due to the increase in adsorption energy of MCM-41 surfaces by the Cu particles.
