Аннотация:A combination of two green chemistry methods—fluid in supercritical carbon dioxide and metal
vapor synthesis—has afforded -Al2O3-based systems modified with Au, Pt, Au–Pt, and Pt–Au nanoparticles. It has been shown that bimetallic nanocomposites in the CO oxidation reaction are more efficient catalysts than monometallic systems. The composition of the Au–Pt/Al2O3 intermetallic compound and its evolution in the course of catalysis have been studied by X-ray photoelectron spectroscopy. It has been demonstrated that the increase in system activity in the course of catalysis is accompanied by a significant rearrangement of the structure and composition of the nanocomposite surface.
