Density function theoretical and experimental study of NH3Â +Â NOx adsorptions on MnOx/TiO2 surface

NH3-TPD curves agrees well with NO conversion curves for MnOx and Mn/TiO2 catalysts. One broad desorption peak in 150-500 °C is present for MnOx and Mn/TiO2 catalysts which are owing to NH3 desorbed by weak acid and Brønsted acid sites.104
