Abstract: |
Titanium with 10s of nm thick n-type anatase oxide films and copper with p-type cuprite oxide films have been prepared, and the photoelectrochemical contributions to the corrosion currents analysed and compared. Titanium samples were analysed in 0.5 M sulfuric acid, and copper samples in borate buffer (pH 9). This dataset contains different measurements supporting mechanisms of photodissolution of oxide-covered metals. Most experiments were performed with white light illumination for copper and 320 nm illumination for titanium, but for reference, other wavelengths were also used, and reference measurements in the dark were conducted. The dataset contains the following experimental results: (i) Photovoltage and photocurrent measurements; (ii) potentiodynamic polarisation curves, including measurements with illumination at selected wavelengths throughout the UV-VIS spectrum, measurements with different oxygen or nitrogen purging, and experiments with different illumination intensities; (iii) full electrochemical impedance spectra, including potential dependent measurements; (iv) capacitance measurements at selected frequencies for Mott-Schottky analysis; (v) in situ UV-VIS reflectance spectra of copper after different exposure times to electrolyte with and without illumination; and (vi) downstream ICP-MS analysis of dissolved titanium with and without illumination. All electrochemical experiments were performed under controlled convection, which enabled a quantification of different contributions to the overall uniform photocorrosion rate of copper and titanium. The dataset contains ASCII files with descriptive filenames and is structured in subfolders indicating the respective methods. A detailed interpretation of the results, and the experimental details associated with the dataset is available in the associated article. |
