Composition, structure, and morphology of the surface of nanodimensional platinum-containing films obtained from sols

Abstract

This work is aimed at studying the composition, structure, and morphology of the surface of nanodimensional platinum-containing silica films synthesized according to the sol–gel technology. An analysis of the data of optical and atomic-force microscopy, X-ray reflectometry, and the method of the Rutherford backscattering made it possible to reveal the regularities of the effect of the synthesis conditions such as the concentration of the initial reagents, duration of sol ripening, and temperature of treatment on the structure and composition of the films.
