Реферат: The properties of gold nanoparticles depend on their size, which is, in turn, determined by the type of a support and method used for their deposition. In this work Au particles were supported on oxides (ZrO2 modified with Ga2O3, CeO2, SiO2, and Al2O3) and ultradispersed diamond by traditional deposition-precipitation from HAuCl4 by ammonia or by proprietary deposition method from gold nanoparticles suspension. Supporting gold on modified zirconia results in formation of large metal particles even at low Au loading. Ultradispersed diamond was found to be promising support for gold catalysts. Electronic state of supported gold particles was found to be strongly depended on preparation method. Deposition-precipitation leads to formation of partially charged metal particles, while deposition from gold nanoparticles suspension results in Au-0. Proposed CO oxidation mechanism on gold particles in the presence of different catalysts was corroborated by DFT calculations.
