Direct decomposition of nitric oxide on alumina-modified amorphous and mesoporous silica-supported palladium catalysts

Palladium catalysts supported on SiO2, MCM-41, [Al]-MCM-41 and on Al2O3-thin-layer- modified SiO2 and MCM-41 were investigated for the direct decomposition of nitric oxide. The catalysts were characterized by X-ray diffraction, BET, SEM, UV-DRS and hydrogen chemisorption. All the catalysts studied were active in the NO decomposition reaction.
