有毒气体一氧化碳因其对人类健康的强烈影响而备受关注。在此，利用一氧化碳在一氧化碳氧化反应中的作用来处理催化剂并增加了一种新的应用。令人满意的是，成功合成了由CuBTC衍生的高度均匀且分散良好的八面体CuO/Cu₂O复合材料，其仍然保留了金属有机框架（MOFs）的原始形态。此外，CuO/Cu₂O复合材料表现出优异的催化性能，这归因于较高的Cu₂O/CuO比例、良好的低温还原性能以及大量的表面活性氧物种。重要的是，本工作所报道的这种简单方法具有普遍性，并且可以容易地扩展到其他金属氧化物，合成基于多种金属有机框架的金属氧化物。（C）2017爱思唯尔有限公司。保留所有权利。
Toxic gas CO has attracted great attention due to their strong impact on human health. Here, CO reaction in CO oxidation was used to treatment catalyst and add a new application. Satisfactorily, highly uniform and well dispersed octahedral CuO/Cu2O composite derived from CuBTC is successfully synthesized, which still retain the original morphology of the MOFs. Moreover, CuO/Cu2O composite showed an excellent catalytic performance, which was ascribed to the higher Cu2O/CuO ratio, good low temperature reduction behavior and a high quantity of surface active oxygen species. Importantly, this simple method reported in this work can be universal and facilely expand to other metal oxides, synthesizing diverse MOFs based metal oxides. (C) 2017 Elsevier B.V.
