Until now, the scientific discussion on the efficiencies of hybrid processes has been sparked by the significant progress in combining ultrasound power with various conventional processes, such as electrolysis, photolysis, catalysis, photocatalysis, and electrocatalysis, in relation to ultrasound-assisted pathways for hydrogen generation . The use of sonication in "silent" procedures has been shown to produce encouraging results that might achieve up to 100% enhancement, according to the last ten of experimental publications on this subject Fig. . Significant achievements have been made in this area over the past 5 years, leading to a doubling of academic publications compared to scientific production before 2018 . Sonophotocatalysis has emerged as a highly promising hybrid process, combining ultrasonic waves and photocatalysis to enhance chemical reactions. Ultrasonic waves generate cavitation bubbles that collapse violently, creating localized extreme conditions of high temperature and pressure, which produce reactive species like hydroxyl radicals (•OH) and hydrogen atoms. Simultaneously, photocatalysis uses light energy to activate semiconductors like titanium dioxide (TiO₂), generating electron-hole pairs to drive redox reactions. The synergy between these processes offers several advantages: ultrasonic waves enhance mass transfer, improve catalyst surface cleaning, and increase reactivity, while photocatalysis accelerates energy conversion and pollutant degradation. This combination maximizes efficiency, accelerates reaction kinetics, and promotes hydrogen production and organic decomposition. As a result, sonophotocatalysis stands out as an innovative, sustainable solution for energy generation and environmental remediation, leveraging the complementary strengths of cavitation and photocatalysis to address pressing global challenges. and "ultrasound" as keyword searches (collected from the Web of Science Core Database).
