Multicomponent metal-organic framework derivatives for optimizing the selective catalytic performance of styrene epoxidation reaction.

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 (≈99%), higher selectivity (≈70%) and better stability compared to MOFs and single component MOF derivatives.
