摘要：
Surface oxygen groups on the carbon nanofiber surfaces are important for the preparation of highly dispersed cobalt catalysts and for the stabilization of the particles against sintering. However, the surface oxygen makes the catalysts easily deactivate during Fischer-Tropsch synthesis by oxidation of metallic cobalt. The activity could be recovered by re-reduction.
