Thermo-temporal physisorption in metal-organic frameworks probed by cyclic thermo-ellipsometry

Temperature-induced sorption in porous materials is a well-known process. What is more challenging is to determine how the rate at which temperature is varied affects these processes. To address this question, we introduce a methodology called "cyclic thermo-ellipsometry" to explore the thermo-kinetics of vapor physisorption in metal-organic framework films.Cyclic thermo-ellipsometry enables exploration of the effects of temperature variation rates on vapor physisorption in MOFs, a key insight for many adsorption-driven applications.
