| 英文摘要 | Novel CeMnaOx (a is the molar ratio of Mn to Ce) catalysts for catalytic decomposition of ozone (O-3) under high GHSV conditions were successfully synthesized by a facile homogeneous precipitation method. CeMn10Ox showed ozone conversion of 96 % for 40 ppm O-3 under relative humidity (RH) of 65 % and space velocity of 840 L.g(-1) .h(-1) after 6 h at room temperature, which is far superior to the performance of the alpha-Mn2O3 (38 %). The ozone decomposition activity of alpha-Mn2O3 increased by a factor of 2.5 with the addition of Ce. XRD, XPS, H-2-TPR, O-2-TPD, EXAFS and DFT calculations data confirmed that cerium-manganese complex oxides with enhanced surface area were formed, which played a key role in the decomposition of ozone. This study provides important insights for developing improved catalysts for gaseous ozone decomposition that can be prepared by a simple method, and promoting the performance of manganese oxides for practical ozone elimination. |
