Abstract POM@MOF composites have aroused much concern regarding their amazing catalytic performance, reliable stability and recyclability; however, it remains great challenge on synthesizing expected POM@MOF composites and catalyzing organic reactions. Herein, a series of three Keggin-POM@rht-MOF-1 (POM = H3+nPMo12-nVnO40, n = 1, (Mo11V1); n = 2, (Mo10V2); n = 3, (Mo9V3)), have been isolated by using a large internal cavity window of rht-MOF-1 to encapsulate the guest molecules of Keggin-POM. X-ray crystallographic analysis reveals that Keggin-POM@rht-MOF-1 composites are of high load efficiency and chemical stability. Upon employed as catalysts on the desulfurization reaction of model diesels and real diesels, the as-synthesized Keggin-POM@rht-MOF-1 composites exhibit high percent conversion of desulfurization up to 96% by Mo9V3 and 90% by Mo9V3, respectively. Its derivatives from both the advantages of the host of rht-MOF-1) and the Keggin-POM guest. The size-matched rht-MOF-1 prevented the leaching of Keggin-POM, while the Keggin-POM retain the reachability of dibenzothiophene (DBT), 1-benzothiophene (BT) and 4,6-dimethyldibenzothiophene (4,6-DMDBT) for the catalyzing the oxidation reactions.

Keggin-POM@rht-MOF-1 复合材料作为多相催化剂实现超深度氧化燃料脱硫

摘要 POM@MOF复合材料因其惊人的催化性能、可靠的稳定性和可回收性而备受关注；然而，合成预期的 POM@MOF 复合材料和催化有机反应仍然是一个巨大的挑战。这里，一系列三个 Keggin-POM@rht-MOF-1 (POM = H3+nPMo12-nVnO40, n = 1, (Mo11V1); n = 2, (Mo10V2); n = 3, (Mo9V3))，有通过使用rht-MOF-1的大内腔窗来封装Keggin-POM的客体分子，从而分离出。X射线晶体学分析表明，Keggin-POM@rht-MOF-1复合材料具有高负载效率和化学稳定性。在用作模型柴油和实际柴油脱硫反应的催化剂后，合成的 Keggin-POM@rht-MOF-1 复合材料表现出高百分比的脱硫转化率，Mo9V3 高达 96%，Mo9V3 高达 90%，分别。它的衍生物来自rht-MOF-1的宿主和Keggin-POM客体的优点。大小匹配的 rht-MOF-1 防止了 Keggin-POM 的浸出，而 Keggin-POM 保留了二苯并噻吩 (DBT)、1-苯并噻吩 (BT) 和 4,6-二甲基二苯并噻吩 (4,6-DMDBT) 的可达性用于催化氧化反应。
