多组分金属有机骨架衍生物在能源和环境领域引起了人们的极大兴趣。然而，大多数的论文集中在单一的MOF衍生物，多组分的MOF衍生物及其催化研究的报道相对较少。在这里，我们报告了一个易于操作的策略，以获得多组分的MOF衍生物，通过处理多组分的MOF在合适的气氛下，在高温下。我们使用ZIF-67作为模板引入Zn，并成功地获得了多组分MOFs。碳化后，与MOF和单组分MOF衍生物相比，具有Co和CoO纳米颗粒的多组分MOF衍生物具有更高的苯乙烯转化率（约99%）、更高的选择性（约70%）和更好的稳定性。
Multicomponent metal-organic framework (MOF) derivatives have attracted strong interest in energy and environmental fields. However, most of the papers focus on single MOF derivatives; reports on multicomponent MOF derivatives and their catalytic studies are relatively few. Here, we report an easy-to-operate strategy to obtain multicomponent MOF derivatives by treating multicomponent MOFs under a suitable gas atmosphere and at high temperature. We used ZIF-67 as a template to introduce Zn and successfully obtained multicomponent MOFs. After carbonization, the multicomponent MOF derivatives with Co and CoO nanoparticles exhibit higher conversion of styrene (approximate to 99%), higher selectivity (approximate to 70%) and better stability compared to MOFs and single component MOF derivatives.
