Studies of adsorption of palladium nanoparticles on silicon oxide using methods of spectrophotometry and atomic force microscopy

Abstract

In this work, the method of UV-VIS spectrophotometry was used to study the adsorption of palladium nanoparticles Pd NPs on silicon dioxide (silochrome S-120). Pd NPs were synthesized using a radiation-chemical method in micelle 0.15 M solutions of the AOT surfactant at different degrees of hydration ω0 = [H2O]/[AOT]. It is shown that adsorption depends on the structure of nanoparticles, conditions of synthesis in reverse micelles, including the ω0 value, which determines the NP size, as well as the chemical and physicochemical properties of the silochrome surface.
