Harvesting Vibration Energy for Efficient Cocatalyst-Free Sonocatalytic H₂ Production over Magnetically Separable Ultra-Low-Cost Fe₃O₄.

ABSTRACT: The cavitation effect is an important geochemical phenomenon, which generally exists under strong hydrodynamic conditions. Therefore, developing an economical and effective sonocatalyst becomes a vital method in capitalizing on the cavitation effect for energy generation. In this study, we first report a novel Fe₃O₄ sonocatalyst that can be easily separated using a magnetic field and does not require any additional cocatalysts for H₂ production from H₂O. When subjected to ultrasonic vibration, this catalyst achieves an impressive H₂ production rate of up to 175 μmol/h/USD (where USD stands for dollars), surpassing most previously reported mechanical catalytic materials. Furthermore, the ease and efficiency of separating this catalyst u
