公開了一種有機-金屬框架材料Ce-UiO-66在降解氯代芳烴類持久性有機污染物(POPs)中的應用。MOF材料具備大比表面積和多孔性質，可以作為載體擔載金屬組分，了金屬的分散度，從而有利于催化劑的活性。主活性組分為Ce,催化劑的比表面積為1000-1200m2/g，微孔結構。有機金屬框架材料Ce-UiO-66可以的低溫催化降解氯代芳烴類POPs。制備條件易控，環境友好，工藝簡單，可操作性好，所得材料有催化，能耗低，，不產生二次污染的特點。

We synthesized a CuO/CeO2 catalyst using a copper ions encapsulated ceria metal-organic framework (MOF) Ce-UiO-66 as the precursor. The CuO/CeO2 catalysts derived by calcining the MOF precursor (the x-CuCe catalysts) showed the better activity and selectivity for the preferential CO oxidation in the H2-rich stream than the CuO/CeO2 catalyst prepared by wetness impregnation (CuCe-im). A temperature window to match the CO conversion and O2 to CO2 selectivity higher than 99.5% at the same time appeared using the x-CuCe catalysts as the catalyst. Raman and XPS results indicated that more oxygen vacancies were formed in the bulk of ceria in the x-CuCe catalysts than that in the CuCe-im catalyst, which could promote the mobility of oxygen. Our results indicated that the surface lattice oxygen and the oxygen vacancies in the bulk of ceria could enhance the catalytic performance of the CuO/CeO2 catalysts.

A CuO/CeO2 catalyst was synthesized by calcining a Cu-containing Ce-MOF precursor, and it exhibited outstanding activity and selectivity for CO preferential oxidation in the H2-rich stream.
