Site na "Mmiri Na-ewe Ihe n'Ikuku" ruo "Enweta Carbon":
Nrite Nobel na-ekpughe ọdịnihu nke ụfụfụ melamine carbonized
- SINOYQX na-enyocha ihe ndị na-adịgide adịgide nke sayensị ihe onwunwe
- Nkwalite Nobel: Otu Sayensị ihe onwunwe si agbanwe ojiji akụrụngwa
N'ọnwa Ọktoba afọ 2025, Royal Swedish Academy of Sciences nyere Susumu Kitagawa (Japan) , Richard Robson (Australia) , na Omar Yaghi (United States) ihe nrite Nobel na Kemistri.
Ọrụ ha nke mbụ na Metal-Organic Frameworks (MOFs) — nke a kọwara dị ka “sponge molecular” — enyela ụmụ mmadụ aka ịchọta mmiri a na-aṅụ site na ikuku kpọrọ nkụ ma na-ejide CO₂ nke ọma na ikuku.
Ike pụrụ iche nke MOF dị n'ihe owuwu ha na-agbanwe agbanwe , nke na-enye ndị ọkà mmụta sayensị ohere ijikwa nha oghere na ebe kemịkalụ kpọmkwem, na-ahọrọ ịmịkọrọ gas, molekul mmiri, ma ọ bụ ụdị ihe ndị ọzọ a na-achọ.
MOFs emepeela oge ọhụrụ nke iji akụrụngwa ikuku eme ihe , yana ngwa ndị dị mkpa gụnyere:
- 🌫️ CO₂ ijide maka atụmatụ nnọpụiche carbon;
- 💧 Iwepụta mmiri site na ikuku ọzara iji mepụta mmiri dị ọcha;
- 🧪 Encapsulation na nkewa nke gas ụlọ ọrụ na-egbu egbu maka mmepụta nchekwa;
- 🔋 Ịkwalite ume ike na ibelata ikuku ikuku.
Ihe ịrịba ama sayensị a na-egosi mgbanwe nke mmadụ na ọdịnihu ebe ọbụna ikuku n'onwe ya na-aghọ ihe onwunwe na-adigide.
- Ụfụfụ Melamine Carbonized: Site na "Ogbo Molecular" ruo "Ogbo Carbon"
Ka teknụzụ MOF na-agbanwegharị nyocha sayensị, SINOYQX na-emepe ụzọ iji nweta ihe ọmụma injinia ya site na ụzọ dị iche - Carbonized Melamine Foam (CMF).
Mgbe ụfụfụ melamine na-enweta carbonization n'okpuru ikuku na-adịghị arụ ọrụ (~800°C) , ọ na-agbanwe ka ọ bụrụ netwọk carbon porous dị fechaa mana siri ike nke nwere nitrogen nwere ihe ndị dị ka:
- Ebe elu dị oke elu (800-2000 m²/g);
- Sistemụ pore dị elu (micro-, meso-, na macropores);
- ezigbo absorption nke photothermal na conductivity;
- Inertness kemịkalụ na nkwụghachi igwe.
"Ogbo carbon" a abụghị naanị na ọ na-amịkọrọ uzuoku mmiri ma na-ejide CO₂ nke ọma, kamakwa ọ na-ejikọ oghere dị n'etiti nkenke sayensị nke ọkwa MOF na ohere itinye ya n'ọrụ n'ogo ụlọ ọrụ mmepụta ihe.
- Ọrụ abụọ: "Ikuku-na-mmiri" na "Carbon Capture"
1️ ⃣ Sistemụ ikuku-na-mmiri (AWH)
Site na mkpuchi elu nke ụfụfụ carbonized na hydrophilic nanolayers (dịka ọmụmaatụ, Zr-MOFs, graphene oxide), ihe ahụ nwere ike ime ka mmiri dị n'ikuku ọbụna na gburugburu ebe iru mmiri dị ala.
N'ehihie, ìhè anyanwụ na-ekpo ọkụ nke ụfụfụ, na-ahapụ ikuku nke na-eme ka ọ ghọọ mmiri mmiri.
Usoro a nke na-amịkọrọ mmiri site na mwepụta ruo na mmiri na-eme ka mmepụta mmiri nke na-enweghị ọkụ eletrik kwe omume - nke dị mma maka ọzara, agwaetiti, na ebe ndị dịpụrụ adịpụ.
2️ ⃣ CO ₂ Njide na Nchekwa
The nitrogen-doped carbon framework nke CMF na-enye saịtị polar na-arụ ọrụ maka mgbasa ozi CO₂.
Nnyocha na-egosi ike adsorption ruru 5.4 mmol / g (na 0 Celsius C), na arụ ọrụ kwụsiri ike mgbe usoro nrụgharị 500 gasịrị.
A na-enyocha CMF maka:
- Industrial flue gas ọcha
- Njikwa gburugburu ebe obibi na usoro nchekwa ike
- Nchacha ikuku na njikwa carbon na ebe data
N'ihi obere oriri ike ya, ike imegharị ya, na nkwụsi ike okpomọkụ ya , CMF na-enye ngwọta dị ọnụ ala, nke a na-agbanwe agbanwe maka ojiji mmiri na carbon ejikọtara ọnụ.

🔹 mmechi:
MOF na-anọchi anya a ọganihu sayensị, ebe CMF na-agụnye mmepụta mmepụta ihe.
Future MOF@CMF mejupụtara ga-ejikọta uru abụọ ahụ iji mee ka ọgbọ na-esote ikuku na mmiri na ikuku carbon na-arụ ọrụ dị elu na nkwụsi ike.
- Ozi SINOYQX: Ụfụ ọ bụla maka Ọdịnihu Na-adịgide adịgide
Dịka otu n'ime ndị na-emepụta ụfụfụ melamine kachasị elu na China , SINOYQX raara onwe ya nye n'ọrụ nke "Ịkwalite Ọdịnihu Akwụkwọ Ndụ site na Mmepụta Ihe."
Site na nkwụghachi ọkụ, nnabata ụda olu, na mkpuchi ọkụ ruo ihe arụrụ arụ carbonized, anyị na-aga n'ihu na-agbasa oke nke ihe ụfụfụ nwere ike nweta.
Ebumnuche anyị na nyocha carbon karịrị ịkwalite arụmọrụ ihe - anyị bu n'obi ime ka mpempe ụfụfụ ọ bụla a ọkara maka ntụgharị akụ ikuku:
iwere mmiri site na ikuku, na-ewepụta carbon site na ikuku, na inye aka na mmepe na-adigide na gram ọ bụla.
- Na-ele anya n'ihu: Site na nchọpụta sayensị ruo mgbanwe mgbanwe mmepụta ihe
Nrite Nobel na-anọchite anya ya ezigbo nke sayensị -
ma ụfụfụ melamine carbonized nke SINOYQX na-egosi na ike nke injinia.
N'ịga n'ihu, SINOYQX ga-arụkọ ọrụ na ụlọ ọrụ nyocha zuru ụwa ọnụ na ndị mmekọ ụlọ ọrụ iji mee ka mmepe na:
- Sistemụ owuwe ihe ubi nke ikuku na mmiri (AWH)
- Ogwe njikwa carbon ejikọtara ọnụ
- Ihe njikwa gburugburu ebe obibi maka usoro nchekwa ike
- Ihe gburugburu ebe obibi na-anọpụ iche nke carbon
agbanye sayensị n'ime ụlọ ọrụ, na ihe n'ime ngwọta -
nke ahụ bụ ụzọ anyị iji nweta ọdịnihu ga-adigide.
