| 英文摘要 | Cycloaddition of CO2 and epoxide into cyclic carbonate is one of the most efficient ways for CO2 conver-sion with 100% atom-utilization. Metal-organic frameworks are a kind of potential heterogeneous cata-lysts, however, high temperature, high pressure, and high-purity CO2 are still required for the reaction. Here, we report two new Zn(II) imidazolate frameworks incoporating MoO4 2- or WO4 2- units, which can catalyse cycloaddition of CO2 and epichlorohydrin at room temperature and atomospheric pressure, giv-ing 95% yield after 24 h in pure CO2 and 98% yield after 48 h in simulated flue gas (15% CO2 + 85% N 2 ), respectively. For comparison, the analogic Zn(II) imidazolate framework MAF-6 without non-3d metal ox-ide units showed 71% and 33% yields under the same conditions, respectively. The insightful modulation mechanisms of the MoO4 2- unit in optimizing the electronic structure of Zn(II) centre, facilitating the rate-determined ring opening process, and minimizing the reaction activation energy, were revealed by X-ray photoelectron spectroscopy, temperature programmed desorption and computational calculations.
