Abstract

Five different compositions of mixed acidic PdCl//2/SnCl//2 catalysts for electroless plating were investigated mainly by electrochemical and x-ray photoelectron spectroscopy measurements, and also by ultraviolet and visible photospectroscopy, transmission electron microscopy, and Auger electron spectroscopy. It is shown that the potential sweep technique using a catalyzed gold electrode in 1M HCl yields voltammograms which depend upon the catalyst activity, and that this technique is applicable for simple diagnosis of the activity of mixed PdCl//2/SnCl//2 catalyst systems. It is found by transmission electron microscopy that large colloidal particles are required for high catalytic activities. X-ray photoelectron spectroscopy showed that these colloidal particles consist of a system in which Pd and Sn atoms have an interaction such as in Pd-Sn intermediates or alloys.
