摘要:
以金属有机骨架Zn(D-樟脑酸)(4,4’-(1,3-丙二基)双吡啶)·H2O(简称Zn-DT)化合物作为膜材料,采用反应晶种法制备Zn-DT膜,考察合成液pH、合成温度与合成时间对Zn-DT晶体的产率及晶型结构的影响。通过X线衍射仪(XRD)、扫描电子显微镜(SEM)、热分析仪(TGA)和纳米划痕仪表征样品的性能。结果表明:pH 6.75、合成温度100 ℃和反应时间10 h为Zn-DT最佳合成条件; 在不高于480 ℃的条件下,Zn-DT晶体具有较好的热力学稳定性。Zn-DT膜对于H2/CO2有较高的分离性能,其分离系数为10.63; 膜层与支撑体间拥有良好的界面结合力。
Abstract:
The yield and the crystallinity of Zn(D-cam)(Tmdpy)·H2O(Zn-DT)under different synthetic conditions, such as pH of synthetic solution, synthetic temperature, and synthetic time were investigated.The morphology and the structure of the samples were studied by X-ray diffraction(XRD),scanning electron microscope(SEM),thermal gravimetric analysis(TGA), and nano-scratch. Under the conditions of pH of 6.75,and synthetic temperature of 100 ℃,and synthetic time of 10 h,Zn-DT crystals with high crystallinity and pure phase could be obtained.Zn-DT crystals had good thermostability lower than 480 ℃.In addition,a continuous Zn-DT membrane with well interfacial adhesion between the membrane and the substrate was fabricated.The separation factor of H2/CO2 mixture reached 10.63.
