Dwoko piny pa CO2 me doko moo ma ki twero tero calo formic acid (HCOOH) obedo yoo maber me lweny i kom rwom me CO2 ma tye ka mede i yamo. Me konyo tic man, gurup pa lutim kwed i Tokyo Institute of Technology guyero gin ma ki yubu ki nyonyo ma nonge oyot ki gu keto i kom gin ma ki lwongo ni alumina support me yubu gin ma twero loko CO2 maber i HCOOH ma romo 90%!
Motoka ma tiyo ki mac obedo gin ma dano mapol maro, ki tyen lok ma pire tek tye ni pe gi cwalo yamo ma ki lwongo ni carbon emissions. Gin marac bot jo mapol, kadi bed kumeno, tye ni pe gi twero wot ki kare malac me charging. Man aye kama moo ma calo moo tye ki adwogi maber. Teko gi ma malo nyutu ni gi twero wot mabor ki gi keto moo oyotoyot.
Lok ki i kom moo onyo diesel me doko moo ma pat twero kwanyo yamo ma ki lwongo ni carbon emissions ki gwoko ber pa moo ma tye ki pii. I fuel cell, me labolle, formic acid twero miyo teko bot injin kun gonyo pii ki carbon dioxide. Ento, ka formic acid ki yubu ki dwoko piny CO2 ma tye i yamo me doko HCOOH, ki dong pii ma kato woko keken.
Medo rwom pa yamo ma ki lwongo ni carbon dioxide i yamo wa ki kony ne i lyeto me wilobo dong obedo lok ma rwate. Kit ma lutim kwed gutemo kwede yoo ma pat pat me cobo peko ni, yoo maber obino—loko yamo ma ki lwongo ni carbon dioxide ma okato i yamo me doko jami ma miyo teko.
Yub me moo ma calo formic acid (HCOOH) ki dwoko piny CO2 i lero ceng okelo tam madwong i kare ni pien yub man tye ki adwogi maber aryo: dwoko piny CO2 ma okato ki bene konyo me dwoko piny teko ma wa tye ka tic kwede i kare ni. peko. Macalo gin maber ma tingo hydrogen ki teko ma malo, HCOOH twero miyo teko ki i lyel kun weko pii keken ma calo gin ma aa ki iye.
Me miyo yub man ma kelo lim ni doko lok ada, ludiro gu yubu jami ma tiyo ki mac ma dwoko piny yamo ma ki lwongo ni carbon dioxide ki kony pa lero pa ceng. Gin man tye ki gin ma kwanyo mac (ma calo, gin ma kwanyo lero) ki gin ma weko electron mapol ma mite me dwoko piny CO2 me doko HCOOH. Pi meno oyabo yenyo jami ma twero tic maber!

Pi tic gi maber ki kit ma gitwero tic kwede odoco, jami ma ki lwongo ni solid catalysts ki tero calo gin maber loyo pi tic man, ki pi mwaki mapol, kero me catalytic pa cobalt, manganese, nickel ki iron-based metal-organic frameworks (MOFs) dong ki temo, ma i kin gii tye ki adwogi maber i kom jami mukene, kadi bed ni pol pa catalysts ma ki yubu ki iron aye gi kelo carbon keken. monoxide ma calo gin ma pire tek, ento pi HCOOH.
Ento, peko man ki cobo oyoto ki gurup pa lutim kwed i Tokyo Institute of Technology (Tokyo Tech) ma lapwony Kazuhiko Maeda aye latela. I kwan ma ki coyo i magazin me Angewandte Chemie, gurup ni gunyutu alumina (Al2O3)-supported iron-based catalyst ma tiyo ki α-iron (III) oxyde (IIIF-Ox) OH; geothite). Gin manyen ma ki lwongo ni α-FeO� OH/Al2O3 catalyst nyutu tic maber me loko CO2 me doko HCOOH ki bene twero tic maber. I kare ma kipenyo gi i kom gin ma gi yero me catalyst, Lapwony Maeda owaco ni: “Wamito ni wa temo jami mapol ma calo catalyts i yub me photoduction ma mito ni wa bed ki tic maber. ma tiyo, ma ki twero tic kwede odoco, ma pe ki kwiri ki ma wel ne lapiny. En omio wa yero jami ma ki nongo i ngom ma calo goethite pi temo wa.
Dul ni otiiyo ki yoo ma yot me yubu gin ma ki lwongo ni catalyst. Gu tiyo ki jami ma ki lwongo ni iron-supported Al2O3 materials me dwoko piny CO2 i rwom me lyeto me ot ma tye ki ruthenium-based (Ru) photosensitizer, electron donor, ki lero ma nen ma tye ki wavelengths ma kato 400 nanometers.
Adwogi ne tye maber atika. Kit ma ki yero kwede jami ma ki yubu ni HCOOH onwongo tye 80-90% ki rwom me 4.3% (ma nyutu tic maber pa jami ni).
Kwoni man nyutu gin mukwongo ma ki yubu ki iron ma twero kelo HCOOH ka ki keto kacel ki gin ma tiyo ki mac ma tiyo maber. Man bene loko i kom kit ma pire tek kwede me tic ki jami ma miiyo kony (Al2O3) ki adwogi ne i kom dwoko piny teko pa mac.
Ngec ma kinongo ki i kwedo lok man twero konyo me yubu jami manyen ma pe ki jami ma ki lwongo ni metal-free catalysts pi dwoko piny yamo ma ki lwongo ni carbon dioxide me doko jami mukene ma konyo. "Kwedo ngec wa nyutu ni yoo me kelo teko ma pe balo kwo pa dano pe tek. Kadi bed ni yoo me yubu jami ma ki lwongo ni catalyst ma yot twero kelo adwogi maber, ki bene ki ngeyo ni jami ma tye i lobo, ka ki miiyo kony bot gi calo alumina, ki twero tic kwede gin ma ki yero me dwoko piny CO2," Prof. Maeda omoko.
