Synthesis, Structure, and Catalytic Properties of Nanocomposites Based on Palladium, Copper(I) Oxide, and Magnetite Nanoparticles Embedded in a Nanocellulose Matrix.

Nanocomposite materials based on palladium, copper(I) oxide, and magnetite nanoparticles embedded in a nanocellulose matrix by precipitation and coprecipitation methods were obtained in situ and ex situ from solutions of the salts of the corresponding metals. Studies of the characteristics of the resulting composites using Fourier transform IR spectroscopy, X-ray diffraction, SEM, and TEM showed that the encapsulated nanoparticles have an insignificant effect on the morphology and structure of nanofibrillar cellulose. The catalytic properties of the nanocomposites were tested in the hydrogenation of nitrobenzene. [ABSTRACT FROM AUTHOR]
