Abstract

In this study, nanorod arrayed thin films of heterostuctured photocatalytic material was fabricated by a simple synthetic route. Accordingly, nanorod-arrays of hematite semiconducting material was grown on a transparent conductive oxide (TCO) glass FTO via a facile hydrothermal method. Followingly, a surounding layer of CdFe2O4 material was secondary grown on the hematite nanorod material. Enhancement of the photoelectrochemical properties of electrodes bases on the heterostructure is significant. Accordingly, the CdFe2O4 layer which is attributed to acting as an electron-hole transportation media helping electron-hole separation efficiently in the system resulting in highly photocatalytic activity. The as-synthesized electrodes have characterized with modern physico-chemical techniques such as SEM, TEM, XRD, UV as well as photocelectrochemical properties. The synthetic experiments of the obtained materials had also systematically optimized for the length of the hematite nanorods and the thickness of the CdFe2O4 layer.
