I-304 stainless steel electrode iqhagamshelwe kwi-photoanode ngocingo lobhedu. Ngaphambi kovavanyo, i-electrode yentsimbi engagqwaliyo engama-304 yayifakwe kwisisombululo se-NaCl esiyi-3.5% iiyure ezi-2 ukuqinisekisa imeko ezinzileyo. Ekuqaleni kovavanyo, xa isibane sivuliwe kwaye sicinyiwe, ii-electron ezivuselelweyo ze-photoanode zifikelela kumphezulu wentsimbi engagqwaliyo engama-304 ngentambo.

Ubuninzi be-photocurrent bulinganiswe kwiseti efanayo ne-OCP. Ukuze kufunyanwe ubuninzi be-photocurrent obuphakathi kwentsimbi engagqwaliyo ye-304 kunye ne-photoanode, i-potentiostat isetyenziswe njenge-ammeter yokumelana ne-zero ukuqhagamshela intsimbi engagqwaliyo ye-304 kunye ne-photoanode phantsi kweemeko ezingezizo ezi-polarized. Ukwenza oku, ii-electrodes zesalathiso kunye nee-counter kwisetingi yovavanyo zazinqunyulwa, ukuze indawo yokusebenza ye-electrochemical isebenze njenge-ammeter yokumelana ne-zero enokulinganisa ubuninzi be-current. I-electrode yentsimbi engagqwaliyo ye-304 iqhagamshelwe emhlabeni we-workstation ye-electrochemical, kwaye i-photoanode iqhagamshelwe kwi-clamp ye-electrode esebenzayo. Ekuqaleni kovavanyo, xa ukukhanya kuvuliwe kwaye kucinywa, ii-electron ezivuselelweyo ze-photoanode ngentambo zifikelela kumphezulu wentsimbi engagqwaliyo ye-304.

Ngexesha lokubeka i-6, amandla aphezulu e-nanocomposite afikelela kwi--550 mV xa kuthelekiswa ne-saturated calomel electrode, kwaye amandla e-nanocomposite afakwe yi-factor ye-6 aphantsi kakhulu kunalawo e-nanocomposite phantsi kwezinye iimeko. Ngoko ke, ii-nanocomposites ze-NiS/TiO2 ezifunyenwe emva kwemijikelo yokubeka i-6 zibonelele ngokhuseleko olungcono lwe-cathodic kwi-304 stainless steel.

Kwi-concentration ye-nitrate yesilivere eyi-0.1 M, amandla okunciphisa xa kuthelekiswa ne-electrode ye-calomel egcwalisiweyo afikelela kwi--925 mV. Emva kwemijikelo emi-4 yokufaka, amandla ahlala kwinqanaba emva kokufaka kokuqala, nto leyo ebonisa uzinzo oluhle kakhulu lwe-nanocomposite. Ngoko ke, kwi-concentration yesilivere ye-nitrate eyi-0.1 M, i-nanocomposite ye-Ag/NiS/TiO2 ephumayo inefuthe elihle kakhulu lokukhusela i-cathodic kwi-304 stainless steel.

Xa ukukhanya okubonakalayo kubetha kumphezulu we-nanowire, iindawo ezininzi ezisebenzayo ze-nickel sulfide ziyavuya ukuvelisa ii-electron, kwaye amandla e-photoionization ayancipha ngakumbi. Nangona kunjalo, xa ii-nanoparticles ze-nickel sulfide zibekwe kakhulu kumphezulu, i-nickel sulfide evuselelweyo iyancitshiswa endaweni yoko, engabi negalelo ekufunxeni ukukhanya.
