Volatile organic compounds (VOCs) are among the major sources of air pollution. Catalytic ozonation is an efficient process for removing VOCs at lower reaction temperature compared to catalytic oxidation. In this study, a series of alumina supported single and mixed manganese and cobalt oxides catalysts were used for ozonation of acetone at room temperature. The influence of augmenting the single Mn and Co catalysts were investigated on the performance and structure of the catalyst. The manganese and cobalt single and mixed oxides catalysts of the formula Mn10%-CoX and Co10%-MnX (where X = 0, 2.5%, 5%, or 10%) were prepared. It was found that addition of Mn and Co at lower loading levels (2.5% or 5%) to single metal oxide catalysts enhanced the catalytic activity. The mixed oxides catalysts of (Mn10%-Co2.5%) and (Mn10%-Co5%) led to acetone conversion of about 84%. It is concluded that lower oxidation state of the secondary metal improves ozone decomposition and oxidation of acetone.

挥发性有机化合物（VOC）是空气污染的主要来源。与催化氧化相比，催化臭氧氧化是一种在较低的反应温度下去除VOC的有效方法。在这项研究中，一系列氧化铝负载的单，混合锰和钴氧化物催化剂被用于室温下的丙酮臭氧化。研究了增加单一Mn和Co催化剂对催化剂性能和结构的影响。制备了通式为Mn10％-CoX和Co10％-MnX（其中X = 0、2.5％，5％或10％）的锰和钴的单氧化物和混合氧化物催化剂。已发现以较低的负载水平（2.5％或5％）向单一金属氧化物催化剂中添加Mn和Co可增强催化活性。（Mn10％-Co2。5％）和（Mn10％-Co5％）的丙酮转化率约为84％。结论是，较低的二次金属氧化态可改善臭氧的分解和丙酮的氧化。
