“…Over the years, various AOPs have been introduced and studied for degrading numerous EOPs found in (waste)water. These processes involve cavitation induced by ultrasonic irradiation [17][18][19][20], photocatalytic oxidation [21][22][23][24][25][26], and Fenton chemistry that relies on the reaction of iron(II) sulfate with hydrogen peroxide (H 2 O 2 ), i.e., Fenton's reagent [27,28]. Additionally, the synergy of AOPs leads to the development of hybrid methods, including ultrasound-assisted Fenton [29], sonophotocatalysis [30,31], photo-Fenton [32,33], and ozone/H 2 O 2 [34][35][36], to achieve enhanced oxidation efficiency.…”

Clear and sanitarily adequate water scarcity is one of the greatest problems of modern society. Continuous population growth, rising organics concentrations, and common non-efficient wastewater treatment technologies add to the seriousness of this issue. The employment of various advanced oxidation processes (AOPs) in water treatment is becoming more widespread. In this review, the state-of-the-art application of three AOPs is discussed in detail: photocatalysis, sonophotolysis, and sonophotocatalysis. Photocatalysis utilizes semiconductor photocatalysts to degrade organic pollutants under light irradiation. Sonophotolysis combines ultrasound and photolysis to generate reactive radicals, enhancing the degradation of organic pollutants. Sonophotocatalysis synergistically combines ultrasound with photocatalysis, resulting in improved degradation efficiency compared to individual processes. By studying this paper, readers will get an insight into the latest published data regarding the above-mentioned processes from the last 10 years. Different factors are compared and discussed, such as degradation efficiency, reaction kinetics, catalyst type, ultrasound frequency, or water matrix effects on process performance. In addition, the economic aspects of sonophotolysis, photocatalysis, and sonophotocatalysis will be also analyzed and compared to other processes. Also, the future research directions and potential applications of these AOPs in wastewater treatment will be highlighted. This review offers invaluable insights into the selection and optimization of AOPs.
