1.1 Introduction
The modern production of textiles, leather, plastics, rubber, medicines, paper, and
other household goods generates a large number of highly carcinogenic wastewater
containing persistent toxic organic compounds, including dyes [1–3]. The magnitude of the damage caused by coloring agents to the environment and human health
induces the use of high-quality physical, chemical, and biological methods of water
purification (adsorption, reagent chemical purification, flocculation, bioremediation,
oxidation, ultraviolet treatment, etc.) [4, 5]. However, the formation of intermediate and secondary contaminants or the simple redistribution of pollutants between
phases limit the use of conventional methods and this only leads to partial, temporary
accumulation of toxicants, and does not guarantee their complete disposal. Therefore, recently a new direction of purification is being actively formed—the method
of photocatalytic degradation of organic toxicants in the aquatic environment. This
method is promising because of its high catalytic activity, the possibility of repeated
