Abstract One-dimensional (1-D) nanostructured materials has become great potential in the field of energy generator and energy conversion because they can provide photogenerated charges via direct electrical pathways and their reduced grain boundaries resulting in superior charge transport properties. 1-D nanomaterials have been synthesized by a number of chemical and physical techniques, including lithographical approach and electrodeposition etc. Among them, p-type CuFeO photoelectrode has rarely been reported as an important semiconductor even it is a promising material to show efficient water photoelectrolysis with visible light illumination. Till date, CuFeO film was reported by spin-coating assisted sol-gel chemistry. In this study, we report CuFeO film is deposited on the FTO glass by reactive ballistic deposition. Metal sources like iron metal and copper metal are evaporative-deposited on the FTO substrate in an oxygen flow condition of ambient of reaction chamber. CuFeO film is grown to get columnar structure by manipulating synthesis parameters such as deposition angle, deposition time, and chamber pressure etc. The crystal structure and morphology of CuFeO film is characterized for photoelectrochemical water splitting reaction.
