Abstract: In this paper, we start with a short introduction to the research background of gas adsorption in the metal-organic frameworks (MOFs) field, and then we highlight the gas adsorption sites and behaviors with the aid of various characterization methods, among which we discuss mainly infrared absorption and Raman scattering, as well as X-ray diffraction and neutron diffraction. In addition, we introduce briefly X-ray spectroscopy because they also play a crucial role in understanding MOFs’ gas adsorption. On the other hand, computational simulations, which can reveal underlying adsorption and working mechanism in microscale, are also discussed. Finally, comprehensive kinetic studies are briefly summarized based on these advanced characterization methods.

Key words: metal-organic frameworks, gas storage, characterization methods
