Catalyst for carbon nanotube synthesis and preparation method thereof

Abstract

The invention discloses a catalyst for synthesis of carbon nanotubes, the catalyst comprises catalytic active particles, a carrier and an inert coating material, the carrier and the inert coating material are catalytic inert materials, the carrier has a porous structure, and the catalytic active particles can be dispersed in the porous structure; the inert coating material is used for coating at least part of the surfaces of the catalytic active particles, the catalytic active particles are effectively protected and stabilized through the synergistic effect of the carrier, the inert coating material and other catalytic inert materials, agglomeration and sintering of the catalytic active particles in a high-temperature catalytic reaction are avoided, and the catalytic activity of the catalyst is improved. The high-temperature stability of the catalyst and the yield and the quality of the carbon nano tube are improved.
