Kev tshawb fawb ntawm "Porous khoom electrolyte reactor" tau ua tiav qhov ua tau zoo ntawm electrochemical txo cov pa roj carbon monoxide thiab nws cov kev siv ncaj qha rau hauv biosynthesis los tsim cov khoom muaj txiaj ntsig zoo bioplastics, tsis yog tsuas yog txhim kho kev siv cov pa roj carbon monoxide tab sis kuj ua rau pom qhov zoo ntawm ib puag ncig zoo. Cov txiaj ntsig kev tshawb fawb tau luam tawm hauv "Nature Synthesis".
Raws li lub ntiaj teb muaj kev txhawj xeeb ntau ntxiv txog cov pa phem yas, kev lag luam plastics compostable tau coj mus rau hauv txoj hauv kev loj hlob tsis tau pom dua. Tsis ntev los no, ib txoj kev tshawb fawb tshiab ua ke los ntawm cov xibfwb ntawm Rice University, University of California, Los Angeles, University of Texas ntawm Austin, thiab University of Wisconsin-Madison qhia peb txoj hauv kev tshiab rau kev tsim cov yas compostable.
Qhov kev tshawb fawb no tau ua tiav cov txiaj ntsig zoo C4+ polyhydroxybutyrate (PHB) bioplastics los ntawm electrochemically txo CO thiab ncaj qha siv nws rau biosynthesis. Cov txheej txheem no tsis tsuas yog txhim kho kev siv cov khoom siv raw, tab sis kuj txo qis kev siv hluav taws xob thiab cov nqi tsim khoom. Dab tsi ntxiv, qhov bioplastic no yog degradable tag nrho thiab muaj kev cuam tshuam me me rau ib puag ncig, ua rau nws yog ib kauj ruam tseem ceeb rau lub hom phiaj ntawm carbon neutrality.
Txoj kev loj hlob ntawm cov thev naus laus zis no qhia txog yav tom ntej ntawm kev tsim cov yas compostable, uas yog, kom ua tiav txoj kev tsim khoom ruaj khov dua los ntawm kev txhim kho kev siv cov khoom siv raw thiab txo qis ib puag ncig hneev taw. Nws muab txoj hauv kev tshiab txhim kho rau tag nrho kev lag luam thiab txhawb cov tuam txhab thiab cov chaw tshawb fawb sab hauv thiab sab nraud kev lag luam los koom ua ke tshawb nrhiav thiab txhim kho cov txheej txheem ntau lawm kom ua tiav cov kev daws teeb meem zoo ib puag ncig thiab kev lag luam yas.
Raws li cov kev siv thev naus laus zis no txuas ntxiv paub tab thiab siv tau, peb muaj laj thawj ntseeg tias cov yas compostable yuav ua lub luag haujlwm tseem ceeb hauv kev txo cov pa phem ib puag ncig, txhawb kev lag luam ncig thiab ua tiav cov hom phiaj ntawm cov pa roj carbon monoxide ntiaj teb. Qhov no tsis yog tsuas yog yeej rau kev siv tshuab, tab sis kuj yog qhov tshwm sim ntawm kev sib koom tes ntawm txhua tus noob neej. Cia peb tos ntsoov rau yav tom ntej kom ntsuab thiab huv dua.
