MnO_x catalytic gauzes are analyzed using BET、SEM and IR before and after treatment. The result shows that the specific surface area, total pore volume and average pore size of MnO_x reduce dramatically, and the infrared absorption band of N-O enhances. The removal mechanism of NO_2 using MnO_x catalyzer is preliminarily believed as absorption-catalysis process.
