Los ntawm "Sau dej los ntawm Cua" mus rau "Capturing Carbon":
Nobel nqi zog nthuav tawm lub neej yav tom ntej ntawm Carbonized Melamine Foam
- SINOYQX Tshawb Fawb Txog Kev Tshawb Fawb Txog Kev Tshawb Fawb
- Nobel Kev tshoov siab: Yuav ua li cas cov ntaub ntawv Science hloov pauv kev siv peev txheej
Thaum Lub Kaum Hli Ntuj xyoo 2025, Royal Swedish Academy of Sciences tau muab qhov khoom plig Nobel hauv Chemistry rau Susumu Kitagawa (Nyiv) , Richard Robson (Australia) , thiab Omar Yaghi (Tebchaws Meskas).
Lawv txoj haujlwm tseem ceeb ntawm Metal-Organic Frameworks (MOFs) - piav qhia tias yog "molecular sponges" - tau ua rau tib neeg muaj peev xwm sau cov dej haus tau los ntawm huab cua qhuav heev thiab ntes tau CO₂ hauv huab cua zoo.
Lub hwj chim tshwj xeeb ntawm MOFs nyob rau hauv lawv cov qauv nanoporous tunable , uas tso cai rau cov kws tshawb fawb kom tswj tau qhov loj me thiab cov chaw tshuaj lom neeg, xaiv cov pa roj, cov dej molecules, lossis lwm hom phiaj.
Cov MOFs tau qhib lub sijhawm tshiab ntawm kev siv cov peev txheej huab cua , nrog rau cov ntawv thov tseem ceeb suav nrog:
- 🌫️ CO₂ capture rau carbon neutrality teg num;
- 💧 Dej sau los ntawm huab cua suab puam los tsim cov dej huv;
- 🧪 Encapsulation thiab kev sib cais ntawm cov pa roj carbon monoxide rau kev tsim khoom zoo dua;
- 🔋 Txhim khu lub zog efficiency thiab txo emissions.
Qhov kev tshawb fawb tseem ceeb no qhia txog tib neeg txoj kev hloov pauv mus rau lub neej yav tom ntej uas txawm tias huab cua nws tus kheej dhau los ua qhov chaw muaj txiaj ntsig.
- Carbonized Melamine Foam: Los ntawm "Molecular Sponge" mus rau "Carbon Sponge"
Raws li MOF thev naus laus zis rov ua dua kev tshawb fawb, SINOYQX tab tom ua thawj coj hauv nws txoj kev tsim kho vaj tse los ntawm kev siv cov khoom sib txawv - Carbonized Melamine Foam (CMF).
Thaum melamine ua npuas ncauj dhau los ntawm carbonization nyob rau hauv ib qho chaw inert (~ 800 ° C) , nws hloov mus ua ib lub teeb tab sis muaj zog nitrogen-doped porous carbon network nrog cov khoom xws li:
- Qhov chaw siab heev (800-2000 m² / g);
- Hierarchical pore system (micro-, meso-, thiab macropores);
- Zoo heev photothermal absorption thiab conductivity;
- Chemical inertness thiab mechanical resilience.
Qhov "pa roj carbon" no tsis yog tsuas yog nqus cov pa dej thiab ntes CO₂ tau zoo xwb, tab sis kuj txuas qhov sib txawv ntawm MOF-qib kev tshawb fawb thiab kev siv tau ntawm kev lag luam.
- Dual Functionality: "Air-rau-Dej" thiab "Carbon Capture"
1️⃣ Cov Tshuab Huab Cua Mus Rau Dej (AWH)
Los ntawm txheej txheej ntawm carbonized ua npuas ncauj nrog hydrophilic nanolayers (piv txwv li, Zr-MOFs, graphene oxide), cov khoom muaj peev xwm adsorb atmospheric noo noo txawm nyob rau hauv qis-humidity ib puag ncig.
Thaum nruab hnub, tshav ntuj sov ua npuas ncauj, tso vapor uas tom qab ntawd condenses rau hauv dej.
Lub voj voog adsorption-release-condensation no ua rau tsis muaj kev tswj hwm, tsis muaj hluav taws xob tsim tau dej - zoo tagnrho rau cov suab puam, cov kob, thiab cov chaw nyob deb nroog.
2️⃣ CO₂ Kev Ntxias thiab Khaws Cia
cov nitrogen-doped carbon moj khaum ntawm CMF muab cov chaw ua haujlwm polar rau CO₂ adsorption.
Kev tshawb fawb qhia tias muaj peev xwm adsorption txog li 5.4 mmol / g (ntawm 0 ° C), nrog ruaj khov kev ua tau zoo tom qab 500 regeneration cycles.
CMF tab tom tshawb nrhiav rau:
- Industrial flue gas purification
- Environmental tswj nyob rau hauv lub zog cia systems
- Huab cua lim thiab tswj cov pa roj carbon hauv cov ntaub ntawv chaw
Ua tsaug rau nws txoj kev siv hluav taws xob tsawg, kev siv rov qab tau, thiab kev ruaj khov thermal , CMF muab cov kev daws teeb meem pheej yig thiab scalable rau kev sib xyaw ua ke ntawm dej thiab cov pa roj carbon.
- MOF × CMF: Qhov twg Science ntsib Engineering
| Performance Aspect | MOF (Metal–Organic Framework) | CMF (Carbonized Melamine Foam) |
| Pore Loj Scale | Nanometer (0.3-2 nm) | Micrometer (10-150 μm) |
| Adsorption Mechanism | Molecular-level selectivity | Hierarchical lub cev + polar adsorption |
| Kev sau dej | ✅ Siab (lab scale) | ✅High (photothermal-pab) |

🔹 xaus:
MOFs sawv cev a kev tshawb fawb, thaum CMFs koom nrog industrial realization.
Yav tom ntej MOF @ CMF cov khoom sib xyaw yuav ua ke ob qho tib si zoo los pab rau tiam tom ntej huab cua-rau-dej thiab carbon capture systems nrog ntau dua efficiency thiab stability.
