A Zr-based MOF with UiO-66 topology, which was defined as Py-UiO-66, has been synthesized by modifying the ligand of p-phthalic acid with a pyridine group. Py-UiO-66 possesses excellent chemical stability in aqueous solutions of pH = 0-13, especially when the pore structure is functionalized by hanging bare Lewis basic pyridine groups. Results of gas adsorption experiment show that Py-UiO-66 has the ability to selectively absorb CH and CO rather than CH. More importantly, Py-UiO-66 has an efficient catalytic effect in CO cycloaddition.
