- Abstract
Through the mechanochemical method, sulfamic acid (SA) is successfully introduced into UiO- 66-NH2 to form SA@UiO-66-NH2. In SA@UiO-66-NH2, the acidic cationic sulfiliminium (S-NH240 +) moiety formed by the bridging bidentate binding mode between SA and the zirconium metal center can release protons, and SA actively participates in the construction of hydrogen-bonded network, thereby accelerating the proton conduction. At 95% RH (relative humidity) and 358 K, the proton conductivity of SA@UiO-66-NH2, can reach 1.42×10-2Scm, which is four orders of magnitude higher than that of the parent framework UiO-66-NH2. Meanwhile, this high proton conductivity can be maintained for at least 90 h.
