The present invention relates to a kind of preparation method of the composite of hollow carbon nanotube loaded transient metal sulfide：PEO PPOX PEO triblock copolymer (P123) is surfactant, and Pehanorm (Tris) is pH buffer, is dissolved in deionized water, P123:Tris:The mass ratio 1 of water:1:1000, stir, obtain clear solution A；With the one kind therein such as iron chloride, cobalt chloride, nickel chloride, copper chloride, ammonium molybdate, ammonium tungstate for source metal, using dopamine hydrochloride as carbon source and nitrogen source, metal salt and dopamine hydrochloride are dissolved in deionized water, the mol ratio of three is 1:(0.5~2):4000, obtain clear solution B；By B solution and solution A according to volume ratio 2:1 mixing, reacts at room temperature 24h, obtains blackish green dispersion liquid；By the centrifugation of blackish green dispersion liquid, washing, dry, then 900 DEG C of calcinings under an ar atmosphere. |
