CALF-20 yana da babban CO2iyawar adsorption saboda kyakkyawar hulɗar watsawa tsakanin CO2da tsarin MOF. Nazarin da suka gabata sun ba da rahoton cewa CALF-20 yana nuna kyakkyawan zaɓi don CO2/N2tsarin. Bugu da ƙari, CALF-20 ya nuna ƙananan H2O loading a low dangi zafi idan aka kwatanta da zeolite 13X, wanda aka kusan amfani da matsayin CO2adsorbent a cikin masana'antu filayen amma adsorbs babban adadin H2O a cikin pores.
Saboda haka, CALF-20 ana sa ran maye gurbin zeolites a adsorbing CO2koda a gaban H2O saboda iskar hayaki da ke fitowa daga masana'antar wutar lantarki da iska mai dauke da danshi yana rage CO2adsorption aiki na adsorbents. Bugu da ƙari, abin sha'awa, rahoton da ya gabata ya ambata cewa tsarin crystal na CALF-20 yana canzawa tare da karuwa a cikin yanayin zafi. Oxalate ligands sun canza daga bis-bidentate zuwa monodentate sannan kuma nisa tsakanin zinc ion da oxygen wanda ya ƙunshi oxalate ya karu daga 2.20 zuwa 2.31 Å.
A gefe guda, an bincika aikin Xe adsorption na CALF-20 kuma ya bayyana cewa CALF-20 ya nuna kyakkyawan zaɓi na zaɓi na Xe don Xe/Kr da Xe/N2tsarin saboda hulɗar van der Waals tsakanin ƙungiyoyin Xe da CH na 1,2,4-triazolate. Bugu da ƙari, CALF-20 ya nuna babban aikin talla don SO2kuma Cl2, Wanda ke da babban van der Waals surface hulɗa tare da MOF surface, a low matsa lamba gefe. A gefe guda, masu binciken sun ba da rahoton cewa CALF-20 ya nuna babban aikin rage yawan electrochemical na CO2zuwa CO saboda tasirin canja wurin caji tsakanin oxalate da triazolate wanda ya ƙunshi CALF-20. Idan aka ba da rahotanni, CALF-20 yana da damar da za a yi amfani da ita ga masu tallan gas da masu haɓakawa don CO.2rage halayen.
