Metal-organic frameworks (MOFs) are promising nanomaterials with unprecedented capacity to store small molecules. Titanium cooperated with NH2-UiO-66 were prepared via post synthesis modifications approach and their structures and properties were characterized by X-raydiffraction,Fourier transform infrared spectroscopy, thermogravimetric analysis, nitrogen adsorption isotherms, and scanning electron microscopy. The resultant titanium cooperated with NH2-UiO-66 showed excellent performance for CO2 adsorption via the formation of oxo-bridged hetero-Zr-Ti clusters. This result clearly demonstrates that the smaller Ti ions exchanged with the Zr ions of NH2-UiO-66 may decrease the pore sizes within the framework to be closer to the ideal pore sizes for CO2 adsorption.
