中国科学院过程工程研究所与国家纳米中心合作,采用水热法制备了一系列CeO2-MnOx复合氧化物催化剂,选取苯作为VOCs的代表物,系统研究了其催化机制。采用水热法,根据不同的Ce/Mn比例制备得到CeO2-MnOx复合氧化物催化剂,通过对其催化活性的检测得到复合氧化物的活性均优于单相组分,并且当Ce/Mn比例为3∶7时,催化活性最佳,进而对该比例制备的复合氧化物的内部结构进行分析,提出相应的催 Institute of Process Engineering, Chinese Academy of Sciences, in cooperation with the National Nanocrystal Center, a series of CeO2-MnOx composite oxide catalysts were prepared by hydrothermal method. Benzene was selected as a representative of VOCs and its catalytic mechanism was systematically studied. The hydrothermal method was used to prepare the CeO2-MnOx composite oxide catalyst according to the different Ce / Mn ratio. The catalytic activity of the composite oxide was better than that of the single phase. The Ce / Mn ratio was 3: 7, the best catalytic activity, and then the ratio of the internal structure of the prepared composite oxides were analyzed, the corresponding reminder
