Abstract
⺠The ultrasonic-modified process introduced ultrasound in the solution impregnation for MnOx/TiO2 catalyst preparation. Ultrasonic process significantly improved the catalytic activity. The NO conversion could reach 90% at 100 °C. The combination analysis of XRD and HRTEM confirmed that manganese oxide was in a highly dispersed state and Ti and Mn had strong interaction. In situ FT-IR studies revealed there were significant amounts of Lewis acidity and high Mn atom concentration on the surface of the novel catalysts.
