Al-Fumaric Acid MOF, feem ntau hu ua Al-FUM, yog Metal Organic Framework (MOF) yam ntxwv los ntawm nws cov tshuaj formula Al(OH)(fum).xH2O, qhov twg x yog kwv yees li 3.5 thiab FUM sawv cev rau fumarate ion. Al-FUM qhia cov qauv isoreticular nrog lub npe nrov MIL-53 (Al)-BDC, nrog BDC sawv cev rau 1,4-benzenedicarboxylate. Qhov no MOF yog tsim los ntawm chains ntawm kaum sib koom hlau octahedra interconnected los ntawm fumarate ligands, tsim lozenge-shaped one-dimensional (1D) pores nrog dawb qhov ntev ntawm txog 5.7 × 6.0 Å2.
Ib qho ntawm cov txiaj ntsig tseem ceeb ntawm Al-MOFs, suav nrog Al-FUM, yog lawv qhov tshwj xeeb hydrothermal thiab tshuaj lom neeg ruaj khov, uas pab txhawb lawv cov khoom loj thiab ua rau lawv tsim nyog rau ntau yam kev lag luam. Tshwj xeeb, lawv ua tau zoo nyob rau hauv kev ua kua adsorption, sib cais, thiab catalysis, qhov twg lawv cov kev ruaj ntseg thiab kev ncaj ncees yog qhov tseem ceeb.
Al-FUM cov dej ruaj khov zoo heev yog qhov khoom muaj nqis tseem ceeb hauv kev tsim cov dej haus. Nws tuaj yeem siv rau hauv cov txheej txheem condensation thiab purification kom muaj kev nyab xeeb thiab zoo ntawm cov dej haus. Qhov tshwj xeeb no yog qhov tseem ceeb tshwj xeeb hauv cov cheeb tsam uas kev nkag mus rau cov dej huv tsis txwv lossis qhov chaw dej muaj paug.
Tsis tas li ntawd, kev hloov pauv ntawm Al-FUM rau hauv MOF-raws li daim nyias nyias nthuav tawm lub sijhawm zoo siab los nthuav nws daim ntawv thov. Cov membranes no tuaj yeem ua haujlwm hauv nanofiltration thiab desalination txheej txheem, pab txhawb lub ntiaj teb kev siv zog los daws cov dej tsis txaus thiab txhim kho cov dej zoo.
Qhov tsis muaj tshuaj lom ntawm Al-FUM, ua ke nrog nws txoj kev nplua nuj thiab kev ua tau zoo, ua haujlwm rau nws ua cov khoom cog lus rau kev siv hauv kev nyab xeeb khoom noj. Nws siv tau tuaj yeem txhim kho kev nyab xeeb ntawm cov khoom noj khoom haus los ntawm kev muab ib txoj hauv kev los kuaj xyuas thiab tshem tawm cov kab mob phem.
Hais txog cov khoom siv lub cev, Al-FUM muaj nyob rau hauv cov hmoov zoo nrog cov particle loj ntawm tsawg dua los yog sib npaug li 20 μm. Qhov loj me me, ua ke nrog thaj chaw tshwj xeeb tshaj li 800 ㎡ / g, ua rau nws muaj peev xwm adsorption siab. Lub pore loj ntawm 0.4 mus rau 0.8 nm tso cai rau qhov tseeb molecular sieving thiab xaiv adsorption, ua Al-FUM tus neeg sib tw zoo tagnrho rau ntau yam kev sib cais.
Hauv cov ntsiab lus, Al-FUM yog ntau yam thiab muaj zog MOF nrog ntau yam kev siv tau, los ntawm kev kho dej thiab kev ua kom huv mus rau kev tsim cov txheej txheem siab heev rau kev pom thiab desalination. Nws cov khoom tsis muaj tshuaj lom, muaj ntau, thiab pheej yig tus nqi kuj ua rau nws muaj zog sib tw rau kev siv hauv kev lag luam khoom noj khoom haus, txhim kho kev nyab xeeb thiab zoo. Nrog rau kev tshawb fawb thiab kev loj hlob tsis tu ncua, Al-FUM tau npaj los ua lub luag haujlwm tseem ceeb hauv kev daws qee qhov kev nyuaj siab tshaj plaws hauv ntiaj teb, tshwj xeeb hauv cov dej thiab zaub mov kev nyab xeeb.
