Multifunctional Polymolybdate-Based Metal-Organic Framework as an Efficient Catalyst for the CO Cycloaddition and as the Anode of a Lithium-Ion Battery.

A three-dimensional polymolybdate-based metal-organic framework (POMOF) consisting of Zn-ε-Keggin unit and organic linker, {[PMoMoO(OH)Zn][BPE]}·[BPE] (), was successfully obtained by the hydrothermal method. Compound is composed of Zn-ε-Keggin units and BPE ligands, featuring a fascinating 5-fold interpenetrating framework with topology. The catalytic performance of compound was investigated, and experiments showed that could effectively facilitate the cycloaddition reaction of CO with epoxides as Lewis acid heterogeneous catalyst. Moreover, compound also was studied as LIBs anode material, and it showed reversible capacity of 546 mA h g at 100th cycle.
