Abstract

In this study, effect of anodization temperature on the photoelectrochemical (PEC) performance of nanostructured hematite films prepared by anodizing the sputtered iron films on the fluorine-doped SnO₂ glass substrate was investigated. It was noted that increasing the anodization temperature would induce the hematite nanostructure developing from film-like to nanorod morphology. Importantly, this morphology transformation is noted to accompany with the enhanced PEC performance up to 0.59 mA/cm² (nanorod structured anodized at 60 °C). Our results clearly demonstrated that the potential of post-treatment using anodization to further enhance the PEC performance of hematite films.
