Journal ArticleDOI
Removal of nitrogen monoxide from exhaust gases through novel catalytic processes
Masakazu Iwamoto,Hamada Hideaki +1 more
TL;DR: In this paper, the present position of decomposition catalysts is mentioned and the catalytic performance of copper ion-exchanged zeolites and Ag-Co3O4 oxides is summarized based on the respective authors' results.
Journal ArticleDOI
Removal of nitrogen monoxide through a novel catalytic process. 1. Decomposition on excessively copper-ion-exchanged ZSM-5 zeolites
TL;DR: In this paper, the number of copper ions that can adsorb NO molecules has been determined by a temperature-programmed desorption technique combined with IR measurement; 94% of Cu{sup 2+} ions in ZSM-5 were active for the adsorption.
Journal ArticleDOI
Removal of nitrogen monoxide through a novel catalytic process. 2. Infrared study on surface reaction of nitrogen monoxide adsorbed on copper ion-exchanged ZSM-5 zeolites
Masakazu Iwamoto,Hidenori Yahiro,Noritaka Mizuno,Wen Xiang Zhang,Yoshihiro Mine,Hiroshi Furukawa,Shuichi Kagawa +6 more
TL;DR: In this article, the adsorption of NO onto copper loaded ion-exchanged zeolites was studied by means of infrared spectroscopy coupled with isotopic techniques, and the binding sites which would bind NO were identified.
Journal ArticleDOI
Cu-ZSM-5 zeolite as highly active catalyst for removal of nitrogen monoxide from emission of diesel engines
TL;DR: In this paper, copper ion-exchanged ZSM-5 zeolite is the most active for the selective reduction of nitric oxide by ethene in the presence of oxygen at temperatures as low as 437 −
Journal ArticleDOI
Influence of sulfur dioxide on catalytic removal of nitric oxide over copper ion-exchanged zsm-5 zeolite
TL;DR: The catalytic activity of copper ion-exchanged ZSM-5 zeolites, used for the selective reduction of nitric oxide by propene in the presence of oxygen was only slightly decreased by the addition of sulfur dioxide as discussed by the authors.
