摘要： The catalytic activity of nanostructured low percent (1%) Co-Ni catalysts on the basis of glass fiber (GF) prepared by a "solution combustion" (SC) method was studied. The catalytic activity of the prepared samples was studied in the reaction of dry reforming of methane (DRM) with CO2. The obtained samples were characterized by a number of physico-chemical methods, including XRD, SEM, TEM, TGA and AFM. The active component was shown to be dispersed in the near-surface layer of the support as nanoparticles of 10-20 nm in size. The active component showed a Co3O4 or (Co, Ni)Co2O4 spinel structure, depending on the catalyst composition. The spinel structure of the active component interacted strongly with the carrier, providing resistance to carbonization, high catalytic activity toward DRM, and high activity and stability in oxidation reactions.
