Article Description

Adsorption of HS on the Ni(dhtp)(H O)·8HO metal-organic framework (known as CPO-27-Ni or MOF-74-Ni) is characterized by in situ powder X-ray diffraction (PXRD), Fourier transform infrared (FTIR), Raman, and UV-visible spectroscopy) and by first-principles periodic boundary conditions calculations. PXRD results show very high stability of CPO-27-Ni framework in the presence of H S. Nevertheless, as evidenced by change in color of the sample from pale yellow to dark green, the adsorption of HS strongly affects the coordination of Ni sites. FTIR results show the reversible molecular adsorption of HS. Experimental and computed energies of interaction reveal good agreement. Quantitative data considering energetic aspects (calorimetric measurements) are also included. This work highlights the fundamentals of H S adsorption onto the CPO-27-Ni framework. © 2013 American Chemical Society.
