Identification of proton-exchange membranes (PEMs) with high proton conductivity and long-term durability is highly important for the development of fuel cells. Herein, an efficient and feasible strategy that features different proton sources and hopping site modifications on the stable UiO-66-NH2 framework for hierarchically improving the proton conductivity is demonstrated. As a result, IM-UiO-66-AS showed the highest superprotonic conductivity of 1.54 x 10(-1) S cm(-1) (80 degrees C, 98% RH) and outstanding long-term durability of at least 100 h, which surpass those of all the reported proton-conducting MOF materials without guest loading. Furthermore, the manufactured membrane could maintain a high proton conductivity of 1.19 x 10(-2) S cm(-1) even with continuous work for at least 40 h under the same conditions, suggesting its great potential for further application in devices.
