The catalysts were characterized by X-ray diffraction, N-2 adsorption-desorption, Brunauer-Emmett-Teller specific surface area, and H-2-temperature programmed reduction. When MnOx/MSU-H was used at three different temperature, 50 degrees C, 80 degrees C, and 100 degrees C, the ozone conversion and COx yield increased with increasing temperature. MnOx/MSU-H exhibited much higher catalytic activity than that of MnOx/Meso-SAPO-34. The high catalytic activity of MnOx/MSU-H seems to be due to the high oxygen ability and structural stability of MSU-H. The CO2 yield was somewhat enhanced by the addition of steam because steam facilitated desorption of the reaction intermediates adsorbed on the catalyst surface, enabling them to be oxidized further.
