Last years the use of sub- and supercritical fluids in the catalyst synthesis is a great
attention. Because of the unique properties subcritical water allow synthesizing the metal-based catalysts with the desired size, dispersity, structure and morphology of the active phase. In this work, we report the study of the structure of polymer-based Pdcontaining catalysts synthesized by hydrothermal deposition. It is shown that the use of palladium chloride as a metal precursor decreases significantly the specific surface area in comparison with that obtained for palladium acetate because of the formation of the larger metal particles on the support surface. Pd is presented by the Pd0 in all studied samples. The complex Pd/PdO particles were observed in the minor amounts. The hydrothermal synthesis allows obtaining the catalysts with the mean particle size 4-8 nm. Thus, hydrothermal method is the permissive way to synthesize the catalysts with the controllable size, structure, and morphology of the metal nanoparticles. |
