Ku-athikili yakamuva eshicilelwe kujenali Imibiko Yesayensi, abacwaningi baxoxa ngokuthuthukiswa kwesistimu yenzwa yegesi ephathekayo yokutholwa kwe-carbon monoxide ngesikhathi sangempela. Lolu hlelo olusha luhlanganisa izinzwa ezithuthukile ezingagadwa kalula ngohlelo lokusebenza oluzinikele lwe-smartphone. Lolu cwaningo luhlose ukuhlinzeka ngesixazululo esihlangene nesisebenzayo sokuqapha amazinga e-CO ezindaweni ezihlukahlukene.
Ucwaningo lwangaphambilini luye lwagqamisa ukubaluleka kwezinzwa zikaphethiloli ezithembekile zokuthola amagesi ayingozi njenge-carbon monoxide. Ukuhlanganiswa kobuchwepheshe besimanje, okuhlanganisa izilawuli ezincane nezinhlelo zokusebenza zeselula, kungathuthukisa ukusebenza nokufinyeleleka kwamadivayisi enzwa uphethiloli. Ukusetshenziswa kwama-heterojunctions e-PN nezinto ezithile ze-nanowire ezifana ne-CuO/copper foam (CF) kuthuthukise nakakhulu ukuzwela nokukhetha kwalezi zinzwa zikaphethiloli.
Inzwa ibixhunywe kumthombo wamandla namathuluzi okulinganisa ukumelana ukuze kulandelelwe ukuguqulwa kokumelana lapho kuvezwe ekugxilweni okuhlukile kukaphethiloli. Yonke idivayisi ibivalelwe egumbini lokulawula ukuze ilingise isimo sangempela sokuthola uphethiloli.
Ukuhlola ukusebenza kukonke kwedivayisi yenzwa kaphethiloli, ukugxila okuhlukile kwe-nitrogen (N2), umoya-mpilo (O2), namagesi e-carbon monoxide (CO) kwahlolwa. Ukugxiliswa kukaphethiloli kusuka ezingxenyeni eziyi-10 ngesigidi kuya kwezingu-900 ngesigidi (ppm) ukuze kuhlolwe ukuzwela nezici zokuphendula zenzwa. Isikhathi sokuphendula senzwa kanye nesikhathi sokuphulukiswa sirekhodwa emazingeni okushisa athile kanye nomswakama ukuze kuhlonzwe ukusebenza kwayo ngaphansi kwezimo ezihlukahlukene zemvelo.
Ngaphambi kokwenza izivivinyo ezisemthethweni zokuzwa igesi, isistimu yokuzwa igesi kufanele ibhekane nenqubo yokulinganisa ukuze kuqinisekiswe izilinganiso ezinembile nezithembekile. Ijika lokulinganisa likhiqizwa ngokudalula inzwa ekugxilweni kwegesi okwaziwayo nokuhlobanisa ushintsho lokumelana nezinga legesi. Impendulo yenzwa iqinisekiswa ngokumelene nezindinganiso ezimisiwe zokuzwa igesi ukuze kuqinisekiswe ukunemba kwayo nokuvumelana ekutholeni i-carbon monoxide.
Singahlinzeka ngezinzwa ezikala izinhlobonhlobo zamagesi, ngale ndlela elandelayo
