Imidazole was introduced into the channels of the metal-organic framework UiO-67 using an evaporation method. The imidazole@UiO-67 composite presents a high proton conductivity of 1.44 × 10(-3) S cm(-1) at 120 °C under anhydrous conditions. With a low activation energy at high temperatures (0.36 eV), the hybrid material can be regarded as a superionic conductor.
