，催化剂呈现颗粒状形貌并具有较大的比表面积（60.56 m

·g

-1

），低温下易还原，具有较好的甲苯催化燃烧性能，完全燃烧温度T

为210 ℃.

Abstract

α-MnO

catalysts are prepared by sol-gel method with KMnO

and fumaric acid as raw materials. The catalysts are characterized by X-ray diffraction (XRD)

scanning electron microscope (SEM)

adsorption-desorption measurement and H

temperature-programmed reduction (H

-TPR). The effect of calcination temperature on the catalytic activity for toluene combustion is investigated. The results indicate that when the calcination temperature is 450 ℃

the obtained α-MnO

nanoparticles possess high specific BET surface area (60.56 m

·g

-1

) and good low-temperature reducibility. Results show that the catalysts have excellent performance in the toluene combustion. The total conversion temperature of toluene i

s 210 ℃.
