CALF-20 Powder Metal Organic Frameworks (MOFs)

CAS: 2589928-73-2

Moralo oa Calgary 20 (CALF-20) o entsoe ka zinki ion (Zn²⁺) joalo ka mohloli oa ion oa tšepe le ion ea oxalate (Ox^2-) le 1,2,4-triazolate (Tri) e le li-ligands tse phelang, tse hlalositsoeng e le [Zn₂Boraro₂Ox]. CALF-20 e na le CO e phahameng₂matla a adsorption ka lebaka la likamano tse khahlehang tsa ho hasana lipakeng tsa CO₂le sebopeho sa MOF.

CALF-20 e na le CO e phahameng₂matla a adsorption ka lebaka la likamano tse khahlehang tsa ho hasana lipakeng tsa CO₂le sebopeho sa MOF. Liphuputso tse fetileng li tlalehile hore CALF-20 e bonts'a khetho e ntle ea CO₂/N₂litsamaiso. Ntle le moo, CALF-20 e bonts'itse tlase ea H₂O ho kenya mongobo o tlase ha o bapisoa le zeolite 13X, e 'nileng ea sebelisoa e le CO.₂adsorbent masimong a indasteri empa e bapatsa palo e kholo ea H₂O ka masobeng. KAR-F33 Namane-20

Ka hona, CALF-20 e lebelletsoe ho nkela li-zeolite sebakeng sa adsorbing CO₂esita le boteng ba H₂O hobane khase ea flue e tsoang ho limela tsa motlakase le moea oa sepakapaka o nang le mongobo o fokotsa CO₂ts'ebetso ea adsorption ea li-adsorbents. Ho phaella moo, ho thahasellisang ke hore tlaleho e fetileng e boletse hore sebopeho sa kristale sa CALF-20 se fetoha ka ho eketseha ha mongobo o lekanyelitsoeng. Oxalate ligands e ile ea fetoha ho tloha ho bis-bidentate ho ea monodentate mme sebaka se pakeng tsa zinki ion le oxygen e etsang oxalate se ile sa eketseha ho tloha ho 2.20 ho ea ho 2.31 Å.

Ka lehlakoreng le leng, ho 'nile ha etsoa lipatlisiso ka ts'ebetso ea Xe adsorption ea CALF-20' me ea senola hore CALF-20 e bontšitse khetho e ntle ea karohano ea Xe bakeng sa Xe/Kr le Xe/N.₂litsamaiso ka lebaka la tšebelisano ea van der Waals pakeng tsa lihlopha tsa Xe le CH tsa 1,2,4-triazolate. Ntle le moo, CALF-20 e bonts'itse ts'ebetso e phahameng ea papatso bakeng sa SO₂le Cl₂, e nang le sebaka se seholo sa van der Waals se sebelisanang le MOF, ka lehlakoreng le tlaase la khatello. Ka lehlakoreng le leng, bafuputsi ba tlalehile hore CALF-20 e bontšitse ts'ebetso e phahameng ea ho fokotsa electrochemical ea CO₂ho CO ka lebaka la phetisetso ea tefiso lipakeng tsa oxalate le triazolate e etsang CALF-20. Ho latela litlaleho, CALF-20 e na le menyetla ea ho sebelisoa ho li-adsorbents tsa khase le li-catalysts tsa CO.₂maikutlo a ho fokotsa.
