A silica-supported cobalt catalyst was prepared by hydrogen dielectric-barrier discharge(H2-DBD)plasma.Compared to thermal hydrogen reduction,H2-DBD plasma treatment can not only fully decompose the cobalt precursor but also partially reduce the cobalt oxides at lower temperature and with less time.The effect of the discharge atmosphere on the property of the plasma-prepared catalyst and the Fischer-Tropsch synthesis activity was studied.The results indicate that H2-DBD plasma treatment is a promising alternative for preparing Co/SiO2catalysts from the viewpoint of energy savings and efficiency.
