Abstract
The two representative vibration modes, thickness-extension and thickness-shear, of resonance oscillation were employed to examine the effects of lattice vibration of acoustic waves on the activity and the selectivity of catalytic reactions. Thickness-extension mode resonance oscillation dramatically increased the activity of acetaldehyde production in ethanol oxidation on Pd and enhanced the selectivity for ethylene production in ethanol decomposition on Ag; only ethylene production was accelerated without changes in acetaldehyde production. On the other hand, thickness-shear mode resonance oscillation promoted neither oxidation nor decomposition of ethanol. From the comparison of lattice displacement, large lattice displacement vertical to the surface is shown to be useful for the activation of catalysis by the metal surfaces.
