Observation of ultra-fine palladium particles on a flat classy carbon electrode with a high resolution scanning electron microscope

Abstract

Ultra-fine palladium particles (>2 nm diam.) which were well aged by electrochemical oxidation-reduction in an aqueous solution of HClO₄ after being vacuum-evaporated on a flat plane of a glassy carbon electrode, have been observed by high resolution scanning electron microscopy (SEM).
