| Abstract | The varied-valence nanocatalyst MnOx was prepared using the oxidation-reduction method under ultrasonic. The optimal synthetic conditions of MnO(x )were explored by adjusting the ultrasonic time, concentration of reaction precursor, drying temperature, and pH of reaction solution. The results indicated that the optimal sample MnOx was synthesized under the condition of ultrasonic time of 20 min, 0.5 mol/L KMnO4, drying temperature of 80 degrees C and pH=7, which showed the super catalytic performance and the time of 100% NO removal rate was as high as 15 h at room temperature. The structure and morphology of the optimal catalyst MnOx were investigated by XRD, N-2-adsorption-desorption analysis, SEM and TEM. Besides, XPS and FT-IR were also applied to explore the catalytic oxidation process of NO removal and the deactivation mechanism of the optimal sample MnOx. It is believed that the interpenetrating and hierarchal pore, the petaloid morphology and weak crystallization structure contribute to the gas adsorption and transmission. The presence of varied-valence Mn and oxygen vacancy can improve the adsorption and activation of NO and O-2, thus, enhancing the NO catalytic removal on the optimal catalyst MnOx at room temperature. |
