Accelerated water stability test and lifetime prediction of metal-organic frameworks

To predict the lifetime of metal-organic frameworks (MOFs) with high water capacity/stability as water harvesters and adsorption heat pumps, a simple accelerated water stability test was developed using liquid water and water vapor in an autoclave. The function obtained from Bnlnauer-Emmett-Teller (BET) surface area loss analysis of MOF-801-P was applied to lifetime prediction, and a long-term stability test of MOF-801-P with liquid water at 65 °C agreed well with the values predicted using the developed test.
