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

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 ω 0 = [H 2 O]/[AOT]. It is shown that adsorption depends on the structure of nanoparticles, conditions of synthesis in reverse micelles, including the ω 0 value, which determines the NP size, as well as the chemical and physicochemical properties of the silochrome surface.
