NOVELTY - Preparing carbon nanotube/three-dimensional graphene network by in-situ synchronous method comprises e.g. placing cation exchange resin in a nickel salt solution, stirring, washing and then drying and adding cobalt salt solution for stirring, filtering and crushing, the stirring resultant resin after pulverization with potassium hydroxide, then ball milling and heat-treating the ball-milled resin in a nitrogen atmosphere, filtering the resulting material after heat-treated with acid solution and drying until the moisture content. USE - The method is useful for preparing carbon nanotube/three-dimensional graphene network by in-situ synchronous method. ADVANTAGE - The method: has simple required reaction equipment and low production cost; and is environmentally friendly, easy to control reaction condition and suitable for industrial production. DETAILED DESCRIPTION - Preparing carbon nanotube/three-dimensional graphene network by in-situ synchronous method comprises (i) placing cation exchange resin in a nickel salt solution, stirring, washing and then drying at 70 degrees C to a moisture content of less than or equal to 10 wt.% and adding cobalt salt solution for stirring, filtering and crushing, (ii) stirring resultant resin after pulverization in step (i) with potassium hydroxide and then ball milling for 1-7 hours at a ball milling rotation speed of 100-500 revolutions/minute; where the mass ratio between resultant resin after pulverization and potassium hydroxide is 1:0.5-1:5, and (iii) heat-treating the ball-milled resin in the step (ii) in a nitrogen atmosphere at 600-1200 degrees C for 0.5-3.5 hours, and filtering the resulting material after heat-treated with acid solution and drying until the moisture content is less than or equal to 1 wt.% to obtain final product.
