Abstract：
:The frequency dependence of H2O2 generation from H2O by a sonochemical reaction was detected experimentally. The results are in good agreement with previous experimental results, which indicate that in sonochemical reactions, frequencies higher than 90 kHz are more effective than frequencies of several tens of kilohertz. The phonon concept of acoustic waves makes it clear that energy depends on frequency, i.e. on the condition of equal phonon density; higher frequency means higher energy. The concentration and accumulation of acoustic energy will be performed through a bubble surface. From the analogy of photoelectric effects, the frequency dependence of the sonochemical reaction was discussed using the phonon concept.
