Diffusion of CH4 and H2 in ZIF-8

Elucidation on the Effect of Operating Temperature to the Transport Properties of Polymeric Membrane Using Molecular Simulation Tool

“…In current work, the diffusivity of gas penetrants has been determined adopting the means of molecular positioning theory, or more commonly known as the Einstein relationship [18][19][20][21][22][23][24]. In Einstein correlation, he related the self-diffusion coefficient of gas particles i, D i to the mean square displacement (MSD) as a function of observation time, such as that presented in (1), through the assumption of particle random walk [25].…”

Ultem®/ZIF-8 Mixed Matrix Membranes for Gas Separation: Transport and Physical Properties

“…Using experimental and mathematical simulation data it was suggested that the structure of ZIFs and MOFs may be somewhat flexible, which could increase [39][40][41] . The idea of the flexibility of ZIF-8 framework has been used to explain CH 4 and N 2 adsorption data in ZIF-8 42,43 . The actual characterization of ZIF-8 flexibility is complex and is not considered in details in this work.…”

Adsorptive removal of arsenic from aqueous solution by zeolitic imidazolate framework-8 (ZIF-8) nanoparticles

“…Substantial works have been done on synthesizing ZIF-8 for gas sorption/separation, catalysis, electrochemical biosensor, as well as functionalized thin films, etc. [10][11][12][13][14]. ZIF-8 could be an attractive sorbent for arsenic removal because of its ultrahigh porosity, high chemical stability and hydrophobic nature.…”
