Ultrasonic agitation can significantly improve catalytic reactions through several mechanisms. These include: - Increased Mass Transfer: The collapse of cavitation bubbles generates microjets and turbulence, improving the diffusion of reactants to the active sites of the catalyst. - Surface Cleaning: Ultrasonic waves can remove surface contaminants and fouling from the catalyst, maintaining its activity over time. - Activation of Catalysts: The high energy environment created by cavitation can activate catalysts by inducing structural changes or creating active sites.
