Sifunde i-electrode yefilimu ye-nitrogen-doped nanocarbon ene-nitrogen concentration engaphansi kuka-10.9 at% eyakhiwe indlela ye-sputtering ye-magnetron (UBM) engalingani.Okuqukethwe kwe-sp(3) kufilimu ye-nitrogen-doped UBM sputtering nanocarbon (ifilimu ye-N-UBM) inyuka kancane ngokugxila kwe-nitrogen.Ukuhlangana okufana ne-nitrogen okufana ne-graphite kuyehla futhi ukubopha okufana ne-pyridine kuyanda ngokukhula kwe-nitrogen.Ifilimu ye-N-UBM inobuso obushelelezi kakhulu obunobunzima obuphakathi kuka-0.1 kuya ku-0.3 nm, cishe obuzimele ekugxilweni kwe-nitrogen.I-electrode yefilimu ye-N-UBM ibonisa iwindi elinamandla elibanzi (4.1 V) kune-electrode yefilimu ehlanzekile ye-UBM (3.9 V) ngenxa yokwenyuka kwayo okuncane kokuqukethwe kwe-sp(3).Umsebenzi we-electrocatalytic ukhuphuke ngokugxila kwe-nitrogen okwandayo, okuphakamisa ukuthi ukusebenza kukagesi kuphezulu uma ukugxiliswa kwe-nitrogen cishe kuku-10.9 ku-%, okuqinisekiswa ukuhlukaniswa okuphezulu kwe-Fe(CN)6(4-).Amandla okunciphisa i-hydrogen peroxide (H2O2) ku-electrode yefilimu ye-N-UBM ashintshile cishe ngo-0.1 V, futhi inani eliphakeme lamanje le-H2O2 lenyuke cishe izikhathi ezingu-4.
