Abstract
The quest for sustainable energy solutions has led to a growing interest in green hydrogen production, with catalyzed sono-photolysis of water emerging as a promising avenue. This perspective highlights the innovative combination of photocatalysis and acoustic cavitation to enhance the generation of green hydrogen from water splitting. By harnessing the power of semiconductor-based catalysts, the sono-photolysis approach capitalizes on solar radiation to initiate water dissociation. Simultaneously, high-intensity ultrasound waves trigger cavitation, creating reactive microbubbles and localized hotspots that further promote hydrogen evolution. Through systematic experimentation and optimization, researchers are investigating the influence of catalyst type, concentration, and ultrasonic parameters on hydrogen production. Excitingly, early results demonstrated a promising synergistic effect between photolysis and sonolysis. These findings traced a new path that is worth being pursued to open the door to scalable, cost-effective, and environmentally friendly green hydrogen production. In this perspective, catalyzed sono-photolysis holds tremendous potential for meeting the world's energy demands sustainably. Its innovative blend of light and sound-driven water splitting paves the way towards a greener future, offering a viable solution for the large-scale production of clean and renewable hydrogen.Ultrasound-induced cavitation and dispersed photocatalysts synergistically decompose water into hydrogen, offering higher efficiency.
