摘要：

Gas-solid interactions and surface intermediates evolution after NO adsorption onto calcined Ce0.62Zr0.38O2 were investigated. The results of adsorption and temperature-programmed desorption of NO were explained using diffuse reflectance Fourier transform infrared spectroscopy (DRIFTS) coupled with temperature-programmed experiments in environmental cell. Surface NO-containing species Such as nitrites and nitrates were identified during evolution of NO on the surface Of CC0.62Zr0.38O2 solid solution at low and high temperature. The ceria-zirconia solid solution was found to be active in deNO(x) reaction in the presence of a "toluene, propene and propane" Mixture. (C) 2008 Elsevier B.V. All rights reserved.
