AI Article Synopsis
- The UiO-66(SH)2 framework underwent postsynthetic oxidation to create UiO-66(SO3H)2, introducing sulfonic acid groups into its structure.
- The oxidized material demonstrated impressive superprotonic conductivity at 8.4×10(-2) S cm(-1) when tested at 80 °C and 90% humidity.
- Its conductivity surpasses all previously reported proton-conducting metal-organic frameworks (MOFs), matching the performance of the leading electrolyte, Nafion.
Article Abstract
Facile postsynthetic oxidation of the thiol-laced UiO-66-type framework UiO-66(SH)2 enabled the generation of UiO-66(SO3 H)2 with sulfonic acid groups covalently linked to the backbone of the system. The oxidized material exhibited a superprotonic conductivity of 8.4×10(-2) S cm(-1) at 80 °C and 90 % relative humidity, and long-term stability of the conductivity was observed. This level of conductivity exceeds that of any proton-conducting MOF reported to date and is equivalent to the conductivity of the most effective known electrolyte, Nafion.
