Synergistic Conductivity Effect in a Proton Sources-Coupled Metal–Organic Framework
Source abstract
Abstract
A water-stable metal–organic framework (MOF)-based composite, H 2 SO 4 @MIL-101-SO 3 H, configured with functionalized sulfonate groups bound to the polymeric backbone and nonvolatile strong acid H 2 SO 4 encapsulated into pores, is demonstrated as a superior proton-conducting material, owing to the resultant multiple proton-transfer pathways. This solid material exhibits a superprotonic conductivity of 1.82 S cm –1 (70 °C, 90% RH) that is comparable to that of other excellent MOF-based proton conductors reported thus far. More importantly, the splendid conductivity (0.92 × 10 –2 S cm –1, −40 °C) of the title material achieves an enormous improvement compared with that of all proton-conducting systems demonstrated at subzero temperatures.
