“…showed that the decolorization efficiency the visible light photoelectrocatalytic process using the α-Fe2O3/TiO2/ACP nanocomposite was higher (94%) compared to those for TiO2/ACP (45%) and Other semiconductors and heterostructures based have been studied at the photoelectatalytic oxidation of azo dyes. The YFeO3/Carbon fiber composite electrode provides high photoelectrocatalytic activity by the removal of RB5 with visible light irradiation and efficiency of 99% after a 60-minute treatment (Liu et al 2021). The Orange II oxidation efficiency on bismuth ferrite (BFO) and 10% La-BFO photoanodes was 55.3% and 84.2%, respectively (Nkwachukwu et al 2021).…”

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.

“…Aromatic fragments of the azo dye molecule are formed as bond breaking products. For example, during the oxidation of RB5, fragments containing benzene rings and naphthalene structures are formed, and the solution becomes completely colorless, although the COD and TOC values are still at a high level (Liu et al 2021).…”
