DRIFT study of the interaction of NO and O2 with the surface of Ce0.62Zr0.38O2 as deNOx catalyst
چکیده انگلیسی

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 Ce0.62Zr0.38O2 solid solution at low and high temperature. The ceria–zirconia solid solution was found to be active in deNOx reaction in the presence of a “toluene, propene and propane” mixture.
