Transport of acetylene adsorbed in CuBTC metal organic framework

Dubinin-Astakhov model for acetylene adsorption on metal-organic frameworks

“…As a new type of porous materials, metal-organic frameworks (MOFs) have attracted much attention for gas separation and storage due to their low density structures, ultra-high surface areas, and tunable frameworks [10][11][12][13][14][15][16][17][18][19][20][21][22]. MOFs have been explored to enhance acetylene uptake capacity, improve its selectivity, and inhibit its polymerization [1,4,[23][24][25][26][27][28][29][30][31][32][33][34][35][36]. Furthermore, various adsorption models (such as Dual-site Langmuir equation [37], Langmuir equation [33], Virial expression [25], and so on [27,31,35,36,38]) were exploited for acetylene adsorption isotherms.…”

Acetylene adsorption on defected MIL-53

“…MOFs have been explored as a promising material for C 2 H 2 storage, because their large surface areas can achieve a high C 2 H 2 capacity at low pressure. In other words, C 2 H 2 storage in MOFs is expected to obtain a high uptake capacity and an excellent C 2 H 2 selectivity without issues of safety and polymerization . For example, Kitagawa et al investigated the adsorption of C 2 H 2 on [Cu 2 (pzdc) 2 (pyz)], which has permanent one‐dimensional channels, can adsorb 42 cm 3 /g C 2 H 2 at room temperature and 1 atm .…”
