Ekibiina ky’abacondoozi kuruga Bugirimaani kikozire eby’ekyoma bibiri ebiine emiringo ebiri kandi ebiine obushoboorozi burungi bw’okureetaho okuhinduka kw’ebintu. Nibibaasa kukoresibwa kureetaho haidrojeni barikusheenya formic acid, n’ebirugiremu bihandiikirwe.
Abanyasayansi abeebembeirwe yunivasite ya Ludwig Maximilian eya Munich (LMU Munich) omuri Bugirimaani bakozire tekinologiya y’okukoresa omushana gw’okukora amaizi g’omubiri erikwegamira aha bicupuri by’amaani ebiri omu plasma bimetallic.
Abacondoozi bakateerana ebicweka bya plasmonic barikuteerana ebicweka bya zaabu (AuNPs) n’ebicweka bya platinum (PtNPs) eby’omuntu omwe.
Omucondooza orikwetwa Emiliano Cortes akagira ati: “Entebeekanisa y’ebicweka bya zaabu ebikye munonga neekora gye munonga omu kuta omutima aha mushana ogurikuruga omu mwanya ogwo n’okureetaho amashanyarazi g’amaani ag’omu kicweka, ebirikwetwa ebicweka ebirikwotsya, ebirikubaho ahagati y’ebicweka bya zaabu.”
Omu ntebeekanisa y’enkora etebekanisiibwe, omushana ogurikureebwa nigukwatagana munonga n’ebicweka by’omubiri ebiri omu kyoma kandi gubireetera kutengeeta omu muringo gw’okuhurira, ekirikureetera ebicweka by’omubiri byona hamwe kugyendera omu bwangu kuruga aha rubaju rumwe rwa nanoparticle kuza aha rundi. Eki nikireetaho akamanyiso kakye aku abakugu barikweta dipole moment.
Nikiruga omu buhango bwa charge n’oburaingwa oburi ahagati y’emyanya y’eshagama nungi n’embi. Eki ku kirikubaho, obucweka obu oburikwetwa nanoparticles nibukwata omushana gw’eizooba mwingi kandi bukaguhindura obutafaari bw’amaani maingi munonga. Nibihwera omu kuhabura oku emibazi erikukora.
Abashomesa b’eby’obwegyese bagyerizeho oburungi bw’ebintu ebirikwetwa plasmonic bimetallic 2D supercrystals omu kuvunda kwa formic acid.
Bakagira bati: “Ekicweka ky’okucondooza eki kikatooranwa ahabw’okugira ngu ezaabu neekora gye munonga kukira platinum kandi ahabw’okugira ngu n’ekintu ekirikutwara H2 ekitarikureetaho kaboni.”
“Okugyezesa okurikwongyerwamu amaani omu kukora kwa platinum ahansi y’omushana nikworeka ngu okukoragana kw’omushana ogurikubaho n’omubaro gw’ezaabu nikirugamu okuhangwa kwa platinum ahansi y’amaani,” nikwo baagira. “Buzima, formic acid ku erikuba neekoresibwa nk’ekintu ekirikutwara H2, AuPt supercrystals nizireebeka nk’ezirikukora gye omu plasma.”
Ekibiriiti ekyo nikyoreka omubaro gw’okukora H2 ogwa 139 mmol ahari buri giraamu y’ekintu ekirikureetaho okuhinduka omu shaaha. Ekibiina ky’abacondoozi kigambire ngu eki nikimanyisa ngu ekintu eki ekirikuhindura omushana hati kiine rikodi y’ensi yoona ey’okukora amaizi g’omubiri (hydrogen) barikubinga amaizi g’omubiri (dehydrogenation formic acid) ahansi y’okukwatwaho kw’omushana ogurikureebwa n’okurabira omu mushana gw’eizooba.
Abanyasayansi nibagira ngu hariho omuringo musya gw’okushoboorora enshonga egi omu rupapura orurikwetwa “Ebintu ebiine amaizi g’omubiri ebirikwetwa Plasmonic bimetallic 2D supercrystals eby’okureetaho amaizi,” ebyashohoziibwe juba omu katabo aka Nature Catalice. Ekibiina eki kirimu abacondoozi kuruga omu yunivasite ya Free eya Berlin, Yunivasite ya Hamburg hamwe na Yunivasite ya Potsdam.
"Omukugaita plasmons hamwe n'ebyoma ebirikukora, turiyo nitutunguura okutunguuka kw'ebintu by'amaani eby'okukoresa omu makorero. Ogu n'omuringo musya gw'okukozesa omushana gw'eizooba kandi gwine n'obushoboorozi bw'okukora ebindi, nk'okuhindura carbon dioxide kuba ebintu by'omugasho," Cole Thes nikwo arikugira. .
