英文摘要	In this research, lanthanum was doped into the framework of MOF-5 to stabilize the spatial structure and to improve its performance. La(NO3)(3)center dot 6H(2)O, Zn(NO3)(2)center dot 6H(2)O and terephthalic acid were used to form La-MOF-5 by an innovative parallel flow-drop solvothermal method. The structure and properties of La-MOF-5 were characterized by the X-ray diffraction (XRD), scanning electron microscope (SEM), thermogravimetry analysis (TGA) and Fourier transform infrared spectroscopy (FTIR). The relationship between microstructure stability and macroscopic properties are illustrated. The results show that the doped lanthanum is beneficial to improve the thermal stability and CO2 adsorption property of MOF-5 because of the improvement of microstructure. On the other hand, the introduction of lanthanum to MOF-5 is beneficial to form porous frameworks and to raise the thermal stability and CO2 adsorption property. The crystallinity, structure, morphology and thermal stability of La-MOF-5 are best at the La-content 2.5 atom%.
