Abstract
Nanocomposite catalysts based on highly dispersed platinum and ceria particles supported on carbon nanotubes were studied. The composites were prepared using the complex (Мe4N)2[Pt2(μ-OH)2(NO3)8] as the platinum precursor. This approach ensured stabilization of platinum nanoparticles, clusters, and single atoms/ions on the surface of both ceria and the carbon nanomaterial. Study of the catalytic activity of the samples showed that highly dispersed metallic platinum species stabilized directly on the surface of carbon nanotubes can efficiently oxidize CO present in low concentrations in a reaction mixture at room temperature, in particular, in the presence of water vapor. However, low-temperature CO oxidation at higher CO concentrations requires formation of new active sites through interaction of platinum ions with ceria particles.
期刊介绍：
Doklady Physical Chemistry is a monthly journal containing English translations of current Russian research in physical chemistry from the Physical Chemistry sections of the Doklady Akademii Nauk (Proceedings of the Russian Academy of Sciences). The journal publishes the most significant new research in physical chemistry being done in Russia, thus ensuring its scientific priority. Doklady Physical Chemistry presents short preliminary accounts of the application of the state-of-the-art physical chemistry ideas and methods to the study of organic and inorganic compounds and macromolecules; polymeric, inorganic and composite materials as well as corresponding processes. The journal is intended for scientists in all fields of chemistry and in interdisciplinary sciences.
