Abstract

The invention relates to a preparation method of a porous carbon nanotube, and aims to solve the problems of easiness in agglomeration, poor dispersity and small specific surface area of a carbon nanotube. The porous carbon nanotube is prepared from a carbon nanotube serving as a raw material through solution preparation, ultrasonic dispersion treatment, acid oxidation, freeze drying, vacuum sintering, acid soaking, washing-suction filtration and drying in vacuum. The preparation method has the advantages of advanced and rapid process, and accurate and abundant data; a product is black powder with the particle diameter of less than or equal to 60nm; pores are uniformly distributed in the surface of the carbon nanotube, and the pore diameters are less than or equal to 10nm; the product purity is up to 99.5 percent, and the specific surface area is increased by 520 percent; the method is an advanced method for preparing the porous nanotube tube.
