“…7 under 5-second ON-OFF cycles of UV light. The films were deposited at times of 5 s and 1 s. Under light, ZnO films exhibit an anodic (positive) current, revealing their n-type semiconductor conductivity [39][40][41]. Photo-responses were measured to be 305.17 A•cm −2 for ZnO films deposited at t on = 5 s, t of f = 1 s when exposed to a constant potential of +0.8 V.…”

To perform electro-catalytic oxidation of alcohols in an alkaline media, zinc oxide (ZnO) thin films were effectively deposited on indium tin oxide (ITO) substrates using the pulsed electrodeposition (PE) method in a zinc nitrate aqueous solution. Analyses of microstructural, photoelectrochemical, and optical characteristics of ZnO thin films were performed as a function of pulsed electrodeposition parameters. XRD analysis was applied to determine structural properties, and SEM and AFM analysis were used to investigate morphological characteristics. X-ray diffraction analyses revealed that the produced films were polycrystalline and had a (002) preferentially oriented, hexagonal wurtzite structure. The morphology of ZnO has improved in the direction of nanorod films, as evidenced by scanning electron microscopy (SEM) and atomic force microscopy (AFM) images. UV transmittance data was used using Tauc's relationship to determine the film's bandgap to be 3.26 eV. The photocurrent response shows that ZnO films have high values, at 305.17 A/cm2, and good optical characteristics. The electrocatalytic oxidation of methanol was finally evaluated on the films. After being optimized in the pulsed electrodeposition mode, ZnO thin film characteristics and methanol electrocatalytic oxidation both saw substantial improvements.

Azo dyes are one of the large classes of water soluble synthetic dyes with a wide range of colors and can be released into the environment when used. Azo dyes belong to one of the most numerous groups of synthetic dyes and are characterized by the presence of an azo group (-N=N-) with two or more symmetrical or asymmetrical aromatic radicals. Processes of photoelectrochemical oxidation using various approaches have been developed for the removal of azo dyes from wastewater. The fundamentals of different photoelectrochemical oxidation processes for azo dyes, such as photoelectrocatalytic oxidation (PEC), photoelectro-Fenton (PEF), and solar photoelectro-Fenton (SPEF) processes, are discussed. The use of different semiconductor materials as electrode materials in photoelectrocatalysis and PEF for azo dye removal, the influence of different parameters on the removal of azo dyes from wastewater, reactor design, combined photoelectrochemical oxidation, including the use of fuel cells, are also considered. The anodic, electrochemical, and photoelectrochemical oxidation processes for azo dye removal is compared. Also shows what products are mainly formed during photoelectrochemical oxidation of azo dyes and how photoelectrochemical oxidation affects the toxicity of azo dye solutions under different conditions.
