Ua aʻo mākou i kahi electrode kiʻiʻoniʻoni nanocarbon nitrogen-doped me ka neʻe ʻana o ka haʻahaʻa haʻahaʻa ma mua o 10.9 ma% i hoʻokumu ʻia e ke ʻano sputtering magnetron unbalanced (UBM).Hoʻonui iki ʻia ka maʻiʻo sp(3) i loko o ka UBM sputtering nanocarbon film (N-UBM film) me ka hoʻonui ʻana i ka ʻike nitrogen.Ke emi nei ka hoʻopaʻa ʻana me ka graphite-like me ka nitrogen a me ka piʻi ʻana o ka hoʻopaʻa ʻana e like me pyridine me ka piʻi ʻana o ka naikokene.ʻO ke kiʻiʻoniʻoni N-UBM he ʻili maʻemaʻe loa me ka awelika roughness o 0.1 a 0.3 nm, ʻaneʻane kūʻokoʻa i ka ʻike nitrogen.Hōʻike ka N-UBM kiʻiʻoniʻoni i kahi puka aniani hiki ke ākea (4.1 V) ma mua o kahi electrode kiʻiʻoniʻoni maʻemaʻe-UBM (3.9 V) ma muli o kona hoʻonui iki ʻana i ka maʻiʻo sp(3).Ua hoʻonui ʻia ka hana electrocatalytic me ka hoʻonui ʻana i ka neʻe ʻana o ka nitrogen, e hōʻike ana i ka nui o ka electroactivity i ka wā e pili ana ka neʻe ʻana o ka nitrogen ma kahi o 10.9 ma%, i hōʻoia ʻia e ka wehe ʻana o Fe(CN)6(4-).ʻO ka hydrogen peroxide (H2O2) hiki ke hoʻemi ʻia ma ka N-UBM film electrode i neʻe ma kahi o 0.1 V, a ua hoʻonui ʻia ke kiʻekiʻe o kēia manawa o H2O2 ma kahi o 4 mau manawa.
