Ultrasonic cleaning involves the use of high-frequency sound waves, typically in the range of 20-40 kHz, to create cavitation bubbles in a liquid medium. These bubbles implode with significant energy, generating local hotspots that can remove contaminants from surfaces. This method is highly effective for cleaning intricate and hard-to-reach areas. In the context of catalysis, ultrasonic cleaning can be particularly beneficial for cleaning catalyst surfaces and reactor components.
