Carbon Dioxide Reforming of Methane by Ni/Co Nanoparticle Catalysts Immobilized on Single-Walled Carbon Nanotubes

We investigated the catalytic reaction of CO2 reforming of methane (CRM) using as-made Ni/Co nanoparticles believed to be immobilized at the tips of single-walled carbon nanotubes (SWNTs). It was found that under the reforming conditions used in this work the turnover rate of the Ni/Co-SWNT catalytic material for CRM was tens to hundreds of times greater than the best existing CRM catalysts. Combined with the long lifetime of this new catalyst, its total turnover times for CRM were significantly greater than those of any other existing CRM catalysts.
