Abstract: High-concentration N2O has been decomposed catalytically with four metal oxide systems which contain s, p, d-block elements. In all cases, the decomposition reaction can be treated as first order with respect to partial pressure of N2O, considering that decomposition product O2 exhibits no or little inhibition effect on the reaction. Optimal preparation conditions for the catalysts have been explored. In particular, chemical interaction between surface metals and carriers has been investigated. The catalysts have been characterized by various analytical techniques and general material issues have also been addressed. Among the four systems studied, Ru/Al2O3 and Mg-Co mixed oxides give best catalytic performance. For example, approximately 6 moles of N2O per kg of the hydroxide/hydrotalcite can be decomposed at 350°C within an hour. © 1998 Elsevier Science B.V. All rights reserved.
