摘要
NO对环境的影响日益严重,如果不有效将其消除掉,将会对环境及人的健康产生极大的危害。因此,目前各国都在研究廉价消除NO污染的方法。采用共沉淀法制备了催化剂CuO/Ce1-x Zr x O2,利用XRD对其晶相进行表征,H2-TPR研究了其氧化还原能力,以NO的转化效率作为评价指标。结果表明:适当比例Zr的加入以及适当比例的CuO能提高活性。
NO increased serious for the environment. If not be eliminated effectively, it would be serious risks on the environment and human health. Therefore, the low- cost ways to eliminate pollution NO were studied in many countries currently. CuO/Ce1-xZrxO2 catalyst was prepared by the method of co - precipitation. XRD was used to characterize the crystalline phase structure of the prepared catalyst. The redox ability of the catalyst was studied by H2 - TPR. Using the conversion efficiency of NO as an evaluation index can make an evaluation of catalytic activity. The test results showed that adding the proper proportion of Zr and CuO can improve the catalytic activity.
