✦ Synopsis


poled single crystal of ferroelectric LiNb03 exposing either the ( -) or ( + ) polar surface was employed as a catalyst support, on which Cu thin films were deposited in thickness range 2.5-IO nm. The catalytic activity for the production of formaldehyde from a CH,OH + O2 mixture was found to higher for the (-) than for the ( + ) polar support in the intermediate thickness range.
