Nanostructurized low percent Co-Ni catalysts on the basis of glass fibers (GF), were synthesized by "solution combustion" (SC) method. Catalytic activity of prepared samples was studied in the reaction of dry reforming of methane (DRM) with CO2. The physico-chemical characteristics of the obtained samples were studied by the methods of XRD, TEM, TGA, AFM, H 2-TPR, DR UV-Vis. The active component was shown to be dispersed in the near-surface layer of support as nanoparticles of 10-20 nm size, which have a Co3O4 or (Co,Ni)Co2O4 spinel structure depending on the catalyst composition. Spinel structure of the active component strong interacting with the carrier is resistant to carbonization and provides high catalytic activity in DRM. Source

Low-percentage catalysts for dry reforming of methane (DRM) with Ni and Co deposited on a glass fiber support by the "solution combustion" (SC) method have been developed. Particle size and state of the active component were studied by XRD, TPR, TEM, SEM and AFM. The active component was shown to be dispersed in the nearsurface layer of support as nanoparticles of size 10-20 nm, which have a Co3O4 or (Co,Ni)Co2O4 spinel structure depending on the catalyst composition. Spinel structure of the active component is resistant to carbonization and provides high catalytic activity toward DRM. Copyright © 2011, AIDIC Servizi S.r.l. Source

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. © 2013 Dalian Institute of Chemical Physics, the Chinese Academy of Sciences.
