Nanosized Co-Ni/Glass Fiber Catalysts Prepared by “Solution-Combustion” Method

Nanostructured low percent Co-Ni catalysts on the basis of glass fibers (GF) were synthesized by a “solution combustion” (SC) method. Catalytic activity of prepared samples was studied in the reaction of dry reforming of methane (DRM) with СО2, CO and butane oxidation reactions. Physico-chemical characteristics of obtained species were studied by XRD, TEM, TGA, AFM, H2-TPR and DR UV-Vis. The active component was shown to be dispersed in the near-surface layer of the support as nanoparticles of size 10–20 nm, which have a Co3O4 or (Co,Ni)Co2O4 spinel structure depending on the catalyst composition. The spinel structure of the active component strongly interacting with the carrier is resistant to carbonization and provides high catalytic activity in DRM, and high activity and stability in oxidation reactions.
