In this work, for the first time, the influence of scaling up the process of titanium dioxide nanotube (TiO2NT) synthesis on the photoelectrochemical properties of TiO2 nanotubes is presented. Titanium dioxide nanotubes were obtained on substrates of various sizes: 2 × 2, 4 × 4, 5 × 5, 6 × 6, and 8 × 8 cm2. The electrode material was characterized using scanning electron microscopy as well as Raman and UV–vis spectroscopy in order to investigate their morphology, crystallinity, and absorbance ability, respectively. The obtained electrodes were used as photoanodes for the photoelectrochemical water splitting. The surface analysis was performed, and photocurrent values were determined depending on their place on the sample. Interestingly, the values of the obtained photocurrent densities in the center of each sample were similar and were about 80 µA·cm2. The results of our work show evidence of a significant contribution to wider applications of materials based on TiO2 nanotubes not only in photoelectrochemistry but also in medicine, supercapacitors, and sensors.

Photoelectrochemical Properties

By methods of anodizing and ion layering were obtained films TiO2/V2O5 and TiO2 / BiVO4. With help of spectral studies of photoelectrochemical and optical properties, the band gap and quantum yield of photoelectrochemical current were determined depends on the ratio of films thickness and the parameters of their synthesis. It is shown, that at synthesized structures UV component quantum yield photoelectrode decreases and contribution of visible light increases.
