NO decomposition on mordenite-supported Pd and Cu catalysts

Palladium and Molybdenum Mono and Bimetallic Catalysts on Modernite for Direct NO Decomposition Reaction

“…In previous works, we have prepared mono-and bimetallic palladium catalysts using different materials as supports such as alumina [19], MCM-41 [11,12] and zeolite NaY [20]. Furthermore, we have studied mordenite as a support for Pd and Cu catalysts [13,14]. These preliminary results showed that mordenite acts as a promoter maintaining the catalyst active for longer time and being more selective than the other used supports.…”

“…Therefore, these materials have been extensively used as inorganic supports for heterogeneous catalysts [15][16][17]. In particular, mordenite is a promising support due to its unique properties such as acidity, unidirectional porous geometry and thermal and hydrothermal stability [8,13,14]. This zeolite has been used as support for Pd catalyst in the NO selective reduction of NO with CH 4 [18].…”

“…The selective reduction of NO x using CO [7], CH 4 [8] and C 3 H 6 [9] as reducting agents, and the direct NO decomposition reaction [10][11][12][13][14], represent a suitable alternative for the decomposition of these contaminant gases; in particular the direct NO decomposition since the process does not require a reducing agent. After the finding that a Cu-ZSM-5 catalyst was able to directly decompose NO, the study of different metals and supports has expanded with the ultimate goal of understanding and improving the catalytic performance [6,10].…”

Insight into copper-mordenite–silica mixtures (CuMOR–SiO2)

“…The catalytic activity of copper-ionexchanged zeolite was early reported by Iwamoto et al [3]. Cu-zeolite catalysts have been successfully used to selectively reduce NO x [4,5]. It is well known that the catalytic activity of different kinds of zeolites depends on the nature of the introduced cations.…”

Aerobic Oxidation of Alcohols Catalyzed by Copper Nanoparticle-Polyacrylamide/SBA-15 as Novel Polymer-Inorganic Hybrid

“…Owing to their large surface area and quantum size effect [3][4][5][6][7][8][9], catalysis by metal nanoparticles (NPs) is one of the most important and attractive research areas.…”
