Abstract

The MnOx nanowires loaded by cerium oxide are synthesized using hydrothermal method and impregnation method. The products exhibit excellent performance on selective catalytic reduction denitration experiments at low temperature. Meanwhile, the obtianed Mn Ce composite oxide are characterized by X-ray power diffraction(XRD) and scanning electron microscopy(SEM), effects of molar ratio of Mn to Ce, catalyst calcination temperature and temperature window on catalytic activity of cerium manganese compound catalyst were also investigated. Activity measurement results indicate that when Mn/Ce mole ratio is 10:4, calcination temperature is 550 °C, catalyst shows optimal performance. When the temperature is 150°C and air velocity is 10 000 h-1, NO conversion rate can reach 88.5%.
