A robust and porous titanium metal-organic framework (Ti-MOF; LCU-402) has been hydrothermally synthesized through combining a tetranuclear TiCa(μ-O)(μ-HO)(HO)(OC-) cluster and a tritopic 1,3,5-benzene(tris)benzoic (BTB) ligand. LCU-402 shows remarkable stability and permanent porosity for CO, CH, CH, CH, and CH gas adsorption. Moreover, LCU-402 as a heterogeneous catalyst can smoothly convert CO under a simulated flue atmosphere into organic carbonate molecules by cycloaddition reactions of CO and epoxides, indicating that LCU-402 might be a promising catalyst candidate in practical applications. We are confident that the identification of a persistent titanium-oxo building unit would accelerate the development of new porous Ti-MOF materials.
一种坚固且多孔的钛金属有机骨架（Ti-MOF；LCU-402）已通过结合四核 TiCa(μ-O)(μ-HO)(HO)(OC-) 簇和三齿 1,3,5-苯（三）苯并羧酸（BTB）配体水热合成得到。LCU-402 对 CO、CH、CH、CH 和 CH 气体吸附表现出显著的稳定性和永久孔隙率。此外，LCU-402 作为一种多相催化剂可以在模拟烟道气氛下通过 CO 和环氧化物的加成反应将 CO 顺利转化为有机碳酸酯分子，这表明 LCU-402 可能是实际应用中有前途的催化剂候选物。我们相信，持久的钛氧建筑单元的识别将加速新型多孔 Ti-MOF 材料的开发。
