Esihlokweni sakamuva esishicilelwe kumagazini i-Scientific Reports, abacwaningi baxoxa ngokuthuthukiswa kohlelo lwenzwa yegesi oluphathwayo lokutholwa kwe-carbon monoxide ngesikhathi sangempela. Lolu hlelo olusha luhlanganisa izinzwa ezithuthukisiwe ezingaqashwa kalula ngohlelo lokusebenza lwe-smartphone oluzinikele. Lolu cwaningo luhlose ukuhlinzeka ngesisombululo esincane nesisebenzayo sokuqapha amazinga e-CO ezindaweni ezahlukahlukene.
Izifundo zangaphambilini zigcizelele ukubaluleka kwezinzwa zikaphethiloli ezithembekile zokuthola amagesi ayingozi njenge-carbon monoxide. Ukuhlanganiswa kobuchwepheshe besimanje, okuhlanganisa ama-microcontroller kanye nezinhlelo zokusebenza zeselula, kungathuthukisa ukusebenza kanye nokufinyeleleka kwamadivayisi okuzwa uphethiloli. Ukusetshenziswa kwama-PN heterojunctions kanye nezinto ezithile ze-nanowire ezifana ne-CuO/copper foam (CF) kuthuthukise kakhulu ukuzwela nokukhetha kwalezi zinzwa zikaphethiloli.
Inzwa yayixhunywe kumathuluzi okulinganisa ugesi kanye nokumelana ukuze kulandelwe ushintsho ekumelaneni lapho kuvezwa amazinga ahlukene kaphethiloli. Lonke idivayisi lalivalelwe egumbini lokulawula ukuze lilingise isimo sangempela sokuthola uphethiloli.
Ukuze kuhlolwe ukusebenza okuphelele kwedivayisi yesensa kaphethiloli, kuhlolwe amazinga ahlukene e-nitrogen (N2), i-oxygen (O2), kanye namagesi e-carbon monoxide (CO). Ukugxila kukaphethiloli kwakusukela ezingxenyeni eziyi-10 ngesigidi kuya ezingxenyeni eziyi-900 ngesigidi (ppm) ukuze kuhlolwe izici zokuzwela kanye nokusabela kwesensa. Isikhathi sokuphendula sesensa kanye nesikhathi sokuphulukiswa kuqoshwa emazingeni athile okushisa kanye nomswakama ukuze kutholakale ukusebenza kwayo ngaphansi kwezimo ezahlukahlukene zemvelo.
Ngaphambi kokwenza izivivinyo zokuzwa igesi ezisemthethweni, uhlelo lokuzwa igesi kumele ludlule enkambisweni yokulinganisa ukuqinisekisa ukulinganisa okunembile nokuthembekile. Ijika lokulinganisa lenziwa ngokudalula inzwa ekugxilweni kwegesi okwaziwayo nokuhlanganisa ushintsho lokumelana nezinga legesi. Impendulo yenzwa iqinisekiswa ngokumelene nezindinganiso zokuzwa igesi ezimisiwe ukuqinisekisa ukunemba kwayo kanye nokuvumelana kwayo ekutholeni i-carbon monoxide.
Singahlinzeka ngezinzwa ezilinganisa izinhlobo ezahlukene zamagesi, kanje:
