In this paper, we show the dominant contribution of an ambient gas to sonochemical reactions in a high-amplitude acoustic resonant mode. A high-amplitude resonant mode in the solution was predicted by the three-layer resonator model, which showed an acoustic amplitude higher than the standard amplitude by a factor of 5. The high-amplitude resonance mode was used to decompose methylene blue in water. The effects of the dissolved gases and the ambient gases of argon, oxygen, and helium on the degradation efficiency were systematically studied using a closed resonant reactor. The maximum efficiency was achieved when the ambient gas was argon regardless of the dissolved gases. The replacement of dissolved gas with ambient gas is enhanced with high-amplitude ultrasonic irradiation.
