The invention relates to the technical field of nano material preparation, in particular to a method for preparing a
fullerene tube through
catalytic chemical vapor deposition. A
catalytic chemical vapor deposition method is utilized, carbon is orderly assembled at a certain temperature by means of a catalyst,
reaction conditions influencing catalyst-carbon
interface bonding are further controlled, and direct preparation of the
fullerene tube from bottom to top is achieved. The
fullerene tube is in a molecular form and is composed of hemispherical fullerene cap ends at the two ends and a carbon
nano tube tubular structure in the middle section, the length-
diameter ratio is larger than 1, the length is within or below the range of short carbon nano tubes, and the
diameter is 0.4-3 nm. According to the method, the design of the catalyst and the control of the dynamic process of
catalytic growth of the
nano carbon material are taken as the core, the direct preparation of the quasi-one-dimensional fullerene tube is finally realized, the
bottleneck that the controllable preparation method of the fullerene tube at the present stage is few and the existing method has more byproducts is broken through, and the method has the characteristics of good
controllability, simple process, low cost, suitability for large-scale preparation and the like; and a new way is provided for realizing efficient and controllable preparation of the fullerene tube.
