Abstract

TiO₂ nanofibers (NFs), grown on Ti sheets by hydrothermal treatment, were coated with Cu₂O nanoparticles (NPs) using sputtering or chemical bath deposition (CBD) in order to improve their photoelectrochemical (PEC) water splitting capabilities as photoanodes. Scanning electron microscopy (SEM) and X-ray photoelectron (XPS) spectroscopy confirmed the production of the desired Cu₂O-TiO₂/Ti hetero-nanostructures, while PEC measurements evidenced a net improvement of the produced photocurrent under standard xenon lamp illumination, compared to the pristine TiO₂/Ti structure. Moreover, it appears that the sputtered composite photoanodes provide a higher photocurrent compared to the CBD made ones, meaning that their oxide/oxide interfaces are of better crystalline quality, supplying a larger number of electrons to the Pt cell cathode for H⁺ reduction to H₂, through the external PEC cell circuit.

期刊介绍： The Journal of Materials Science publishes reviews, full-length papers, and short Communications recording original research results on, or techniques for studying the relationship between structure, properties, and uses of materials. The subjects are seen from international and interdisciplinary perspectives covering areas including metals, ceramics, glasses, polymers, electrical materials, composite materials, fibers, nanostructured materials, nanocomposites, and biological and biomedical materials. The Journal of Materials Science is now firmly established as the leading source of primary communication for scientists investigating the structure and properties of all engineering materials.
