Nyob rau hauv hydrogenation cov tshuaj tiv thaiv ntawm cov tshuaj lom neeg kev lag luam, hydrogen cracking feem ntau yuav tsum muaj qhov kub thiab kev ntsuas thiab kev nyab xeeb ntau dua. Ntev ntev, ua tiav hydrogen tawg nyob rau hauv qhov kub ib txwm muaj lub hom phiaj tseem ceeb qhia los ntawm cov kws tshawb fawb.
Raws li cov xov xwm tshiab ntawm kev tshawb fawb Suav, lub hom phiaj ntawm cov kws tshawb fawb ntawm chav dej hauv chav tsev nyob rau hauv cov khoom siv hluav taws xob hauv chav kawm hauv chav dej hauv kev lag luam roj carbon monoxide
Qhov no ua haujlwm tshiab hauv kev nce qib ntawm photocatalytic hydrogency splitting tau ua tiav los ntawm cov kws tshawb fawb WANG FENGESTO los ntawm University of University Tranieste, Ltalis, ntawm lwm tus. Cov ntawv tshawb fawb ntsig txog luam tawm online hauv kev kawm thoob ntiaj teb yog cov lus qhia thaum ntxov 'thaum ntxov lub Cuaj Hlis 5, lub sijhawm Beijing.
Tshawb nrhiav WANG FENG, tus sau sau cov ntawv, qhia txog ib qho ntawm cov kev lag luam ntawm hydrogenation hauv kwv yees li ib hlis tshuaj tiv thaiv cov txheej txheem. Ib qho ntawm cov kauj ruam ntawm hydrogenation yog hydrogen zog, uas suav nrog ob qho tib si corolytic thiab heterolytic cov txheej txheem. Ntawm lawv, Heterolytic cleavage ntawm hydrogen ua cov tsiaj polar, uas yog cov muaj nuj nqi ntau pawg ntawm cov khoom lag luam muaj txiaj ntsig zoo thiab txo cov khoom tsis zoo.
Hauv txoj kev tshawb fawb no, cov pab pawg tshawb fawb tawg los ntawm kev siv hluav taws xob yav tas los thiab qhov ua tiav rau kev tsim kho cov tshuaj tua hluav taws xob thiab qhov ua tiav rau hydrogen heterolyees raws li tej yam kev mob huab cua.
Kev Tshawb Fawb Pab Pawg siv kub / titanium dioxide ua qauv catalalyst. Los ntawm kev tshaj tawm titanium dioxide nrog ultraviolet teeb, lub tshuab hluav taws xob uas tsim tawm tuaj yeem hloov mus rau cov nanoparticles kub thiab tau cuab. Meanwhile, muaj cov kev tsis haum ntawm cov kub-}}}}}} paphares, qhov twg Photogenerated qhov tuaj yeem raug cuab. Txij ntawm no, lub qhov thiab hluav taws xob yog nyob ntawm kub-}}}}}} kub sab nraud hluav taws xob hauv tshuab hluav taws xob- lub qhov khub. Yog li ntawd, thaum lub hauv paus hluav taws xob - qhov kev ua haujlwm ntawm cov kub / titanium dioxide hauv catalysiziazide in catalyzide nce linarly nrog lub zog muaj zog.
Tom qab, pab pawg tshawb fawb ntxiv tau tshawb pom qhov zoo ntawm cov khoom siv hydrogen cais, cov khoom siv roj carbon dioxide tag nrho, nrog rau cov khoom lag luam kub, Tom qab ntawd, los ntawm ib lub cuab yeej uas hloov siab rau kev coj mus rau Ethylene, carbon dioxide tuaj yeem muaj ntau ntxiv rau ntau dua 1500 teev yam tsis muaj kev tiv thaiv.
Pab pawg tshawb fawb taw qhia tias txoj kev txhim kho tshiab ntawm cov photocatalytic rau cov roj av, thiab kub / cerium oxadate, thiab kub / cerium oxadate
Wang Feng tau hais tias dhau los ntawm cov khoom siv hluav taws xob tsis zoo xws li siv cov khoom siv hluav taws xob thiab cov pa roj hmab kom zoo dua qub
Nws tau tshaj tawm tias yav tom ntej, pab pawg tshawb fawb yuav ua rau qhov no, muab cov qauv tshuaj tiv thaiv tshiab rau kev hloov kho thiab kev hloov pauv ntawm cov tshuaj lom niaj hnub.
