Ischehko E. Catalytic transformation of small moleculars by complex systems based on 3d- and 4d-elements

The CO oxidation on oxides, based on Fe,Mn, Cu, Co catalysts was investigated. Increasing of oxygen in hydroxyl groups on a surface of the samples increases their catalytic activity. Magnetic component of iron with the sizes of clusters 20-25 nm is favourable for formation of active catalysts. (2 -Form of adsorbed CO is favourable for the CO oxidation. It is shown, that the hysteresises on dependencies of a degree of conversion CO in СО2 vs temperature can be explained by heterogeneous-homogeneous mechanism. Catalytic properties of supported Pd, Pd-Ag catalysts were investigated. It is shown that catalytic activity of the supported catalysts is decreased by set of supporters such as Al2O3, diamond, PAC, graphite, ZrО2. The investigation of catalytic activity of Fe-Co, Co-Mo and Fe-Mo alloys supported on carbon carrier in ammonia synthesis has shown that the dissociated nitrogen forms are favourable for high catalytic activity.
