Study of dispersed states of CuO on Ce0.5Zr0.5O2 and its influence on CO oxidation activity(CuO在Ce0.5Zr0.5 O2上的分散状态及其CO氧化性能的研究)
以硝酸铈和硝酸锆为原料，采用共沉淀法制备了不同摩尔比（0，0.1，0.2〜0.9，1.0）的CemZr1-mO2样品.并以Ce0.5Zr0.5O2为载体，采用浸渍法负载不同含量的CuO，在色谱流动法上考察其对CO的氧化活性.并用XRD，TPR和BET等技术对CuO/Ce0.5Zr0.5O2各样品进行了表征.结果表明，当CuO负载量为5.0%时，其CO的氧化活性最高.XRD测定表明其氧化活性的高低与铜物种在Ce0.5 Zr0.5O2上的分散状态有关.TPR结果亦显示活性的高低与Ce0.5Zr0.5O2上分散较好的铜物种的α还原峰及分散较差的γ还原峰的峰温及形状有关....
