摘要: 采用软模板水热法制备了不同Cu/Ce物质的量之比的CuO-CeO2(nCu:nCe=1:9、2:8、3:7、4:6、5:5、6:4、7:3)催化剂。考察了nCu:nCe和制备方法(软模板水热法和无模板共沉淀法)对CuO-CeO2催化剂低温催化氧化CO性能的影响,并采用XRD、N2-吸附脱附、TEM、H2-TPR和XPS等表征手段对催化剂的结构、氧化还原特性和表面化学状态等进行了分析。结果表明,随着nCu:nCe的增加,CuO-CeO2催化剂的CO催化氧化活性先升高后降低。当nCu:nCe=5:5时,催化剂在100℃时CO转化率即达到90%以上。采用软模板水热法制备的CuO-CeO2催化剂大的比表面积、狭窄的孔道分布结构、活性CuO物种高的分散状态和CuO与CeO2之间存在强相互作用是其具有优异的CO催化氧化活性的主要原因。
