Hydrogen dielectric-barrier discharge(H_2-DBD)plasma was successfully used to prepare carbon nanotubes(CNTs)-supported cobalt(Co) catalyst.The H_2-DBD plasma treatment simultaneously decomposed and reduced the cobalt precursor at a lower temperature and in a shorter time than the conventional method(calcination and hydrogen reduction).It is considered that the H_2-DBD plasma method can remarkably decrease the amount of energy input compared to traditional methods used to prepare the Co-based catalyst in Fischer-Tropsch synthesis(FTS).Results showed that the Co catalyst prepared by H_2-DBD plasma had an equivalent catalytic performance for FTS as that prepared using the conventional method in calcination and hydrogen reduction,thereby determining that H_2-DBD plasma was an effective alternative treatment for preparing the Co/CNTs catalyst for FTS.This technology will provide a new strategy for preparing catalysts in other catalysis processes.
