A superfast pathway for zeolite was established with nano-channels by Dalian Institute of Chemical Physics. The adsorption configurations and diffusion processes of different long-chain alkanes in different zeolite channels were directly measured via SRIR microspectroscopy. These results provide direct experimental evidence for theoretical simulations. Based on the adsorption rate diffusion experiments, it was determined that the diffusion trend and pore size of short- and long-chain alkanes showed completely opposite results for zeolites. Furthermore, SRIR experiments verified the deformation differences between long-chain molecules with different pore sizes. (Nature Communications, 2023, 14: 1735)
