Then, highlighting the advantages of hydrogen generation from different solid waste as plastic sources and biomass by heterogeneous photocatalysis and the evolution of carbon-based materials in this area, with the recent application in this field, also describing the potential of ultrasonic application towards this technology. As a potential technology for hydrogen generation, ultrasound-assisted approaches will eventually be briefly reviewed along with its limitations and difficulties, investigating sonocatalysis, sonoelectrocatalysis, and sonophotocatalysis at a molecular level to shed light on how to integrate sonication with more traditional methods of producing hydrogen. This perspective would effectively push forward the progress of biomass valorization and understanding the mechanism of sonophotocatalytic as a great combination for hydrogen generation and we hope this review can inspire development of more creative work and help clarify some directions for research and development in this specific application area in the future.
