Abstract

Abstract Rutile titanium oxide (TiO 2 ) synthesized in copper containers, was spin-coated with different surface passivation layers such as magnesium oxide (MgO), calcium carbonate (CaCO 3 ), zirconium oxide (ZrO 2 ), and tin oxide (SnO 2 ). The deposition of these passivation layers on TiO 2 confirmed with the help of XRD and EDX analysis, leads to changes in surface morphology induced by the passivation layers demonstrated by FE-SEM imaging. The highest photoconversion efficiency obtained for TiO 2 electrode with MgO passivation layer (6.05%), respective incident photon conversion efficiency was 52%. After introduction of passivation layers on the TiO 2 nanostructure, electron lifetime increased from 0.48 ms to 0.65 ms and charge transfer resistance decreased from 36.9 Ω cm (pristine TiO 2 electrode) to 20.16 Ω cm (MgO passivation layer).
