Increased Catalytic Activity

Clearly, it would be advantageous if the catalytic activity and/or the selectivity of a heterogeneous catalyst could be varied by a signal given to the catalyst.

Recent studies by scientists at the Nagaoka University of Technology, Japan, have lead them to conclude that remarkable enhancements in the catalytic activity of a thin film palladium catalyst supported on ferroelectric lead strontium zirconium titanate and lithium niobate substrates can result from resonance oscillation of the material (Y. Inoue and Y. Ohkawara, Jr. Chem. Soc., Chem-Commun., 1995, (20), 2101–2102).

Using the resonance oscillations generated by low-frequency voltages of the ferroelectric substrates, remarkable 250 to 300 fold increases in activity of the catalyst surfaces were found during ethanol oxidation. I.E.C.
