Abstract

The disclosure provides for thermal, solvent, and / or acid resistant metal organic frameworks and the use of these frameworks in devices and methods for gas separation, gas storage, and catalysis. The disclosure further provides for MOFs that are strong solid acids, and the use of these strong solid acid MOFs in catalytic devices and catalytic methods.

Description

[0001] Cross References to Related Applications [0002] This application claims priority under 35 USC § 119 to Provisional Application Serial No. 61 / 941,791 filed February 19, 2014, the disclosure of which is incorporated herein by reference. [0003] Statement Regarding Federally Funded Research [0004] This invention was made with government support under Grant Nos. DE-AC02-05CH11231 and DE-SC000105 awarded by the U.S. Department of Energy. The US Government has certain rights in this invention. technical field [0005] The present disclosure provides acid-resistant, solvent-resistant, and / or heat-resistant metal-organic frameworks (MOFs), including solid acid MOFs (sa-MOFs); and uses of said MOFs for gas adsorption, gas separation, and catalysis . Background technique [0006] Metal-organic frameworks (MOFs) are porous crystalline materials built by linking metal clusters called secondary binding units (SBUs) and organic linking moieties. MOFs have high surface area...
