Preparation of carbon nanotube-loaded molybdenum doped cobalt trioxide catalyst

The invention relates to the preparation of a carbon nanotube-loaded molybdenum doped cobalt trioxide catalyst. The preparation method comprises the following steps: self-assembling a carbon nanotubeserving as a conductive substrate, cobalt-containing metal salt serving as a cobalt source and molybdate as a molybdenum source to form a precursor similarly shaped tomatoes on sticks; then, placing the quantitative precursor into a porcelain boat, sealing the porcelain boat in a quartz tube, feeding high-purity argon gas, performing heating and cooling in sequence, and then replacing the argon gas by air; and finally, naturally cooling the quartz tube to a room temperature, and performing pyrolysis and oxidization to obtain the target product Mo-Co3O4/CNTs. The preparation method of the composite material, provided by the invention, has the advantages of easy availability of raw materials, simple synthesis, low cost, large-scale easy preparation and the like. The material is relatively small in particle size, hig
