Реферат: The method of self-propagating high temperature synthesis was used for preparing highly efficient catalysts from Ni-Al alloys corresponding to the basic composition of Ni3Al intended for the process of carbon dioxide methane conversion. A low-dose modifying of platinum was carried out using ion implantation. Catalysts were tested in the course of carbon dioxide methane conversion at an atmospheric pressure and within the temperature range of 600-900 °С. It is demonstrated that the microstructure of the samples exerts a significant effect on the catalytic activity and stability of their functioning. A maximum activity is inherent in nanostructured catalysts those represent Pt clusters with size ranging from 0.3-0.5 to 3-5 nm, stabilized within the structure of intermetallic compound Ni3Al and Al2O3. Using the methods of XRD, SEM, EDS, HRTEM, XPS, DSC-TG it was demonstrated that unmodified catalysts undergo a partial coking in the course of methane conversion into synthesis gas, whereas samples modified with platinum are stable and almost non-affected by deactivation due to carbonization.
