Carbon Dioxide Reforming of Methane over Co-Ni Catalysts

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 near-surface 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.
