Title: | Pt/Mg-Ce-O catalyst for NO/H2/O2 lean de-No x reaction | Authors: | Costa, Costas Efstathiou, A. M. |
Major Field of Science: | Natural Sciences | Field Category: | Chemical Sciences | Keywords: | Lean de-NOx;NO reduction;Supported platinum;Mixed metal oxides | Issue Date: | Aug-2004 | Source: | Environmental Chemistry Letters, 2004, Volume 2, Issue 2, Pages 55-58 | Abstract: | The NO/H2/O2 reaction was studied under oxidizing conditions in the 100-400 °C range over 0.1 wt% Pt supported on various metal oxides such as MgO, CeO2, SiO2, La2O3, CaO, Y2O3 and TiO2. The Pt/MgO and Pt/CeO2 catalysts showed good catalytic behaviours. Here, we find that the Pt/Mg-Ce-O catalyst, prepared from MgO and CeO2 by the sol-gel method, is a very active and selective catalyst towards N2 formation in the whole 100–400 °C range. This catalyst appears to be the most active, selective and stable one ever reported in the literature for the NO/H2/O2 reaction, even in the presence of 5%v H2O or 20 ppmv of SO2 in the feed stream. | URI: | https://hdl.handle.net/20.500.14279/11041 | ISSN: | 16103661 | DOI: | 10.1007/s10311-004-0071-x | Rights: | © Springer-Verlag 2004 | Type: | Article | Affiliation : | University of Cyprus | Publication Type: | Peer Reviewed |
