METHOD FOR PRODUCTION OF APPLIED CATALYST AND METHOD FOR PRODUCTION OF CARBON NANOTUBES Russian patent published in 2010 - IPC B01J37/00 B01J21/00 B01J27/00 B82B3/00 C01B31/00 

FIELD: nanotechnologies.

SUBSTANCE: invention relates to the field of nanotechnology, in particular to method for development of carbon nanotubes (CNT). Method is described for production of applied catalyst including application of catalyst precursor solution onto carrier, its further drying, baking and restoration in hydrogen flow, differing by the fact that catalyst precursor is represented by polyoxometalates of discrete structure with the following composition [H₄Mo₇₂Fe₃₀O₂₅₄(CH₃COO)₁₀{Mo₂O₇(H₂O)}{H₂Mo₂O₈(H₂O)}₃(H₂O)₈₇], or [Mo^v ₁₂O₃₀(µ₂OH)₁₀H₂{Ni^II(H₂O)₃}₄], or [Mo^v ₁₂O₃₀(µ₂OH)₁₀H₂{Co^II(H₂O)₃}₄], or K₉Na[Se₂W₁₈Cu₃O₆₆(H₂O)₃]·16H₂O, or Cs₄[Fe₄(H₂O)₁₀(β-SeW₉O₃₃)₂]·21H₂O, and carrier is represented by porous carrier with developed specific surface. Also method is described for production of CNT, including decomposition of carbon source at high temperature in presence of above-mentioned catalyst, besides process is performed in reducing medium, obtained product is cooled down to room temperature.

EFFECT: catalyst has been produced, which has permanent composition of particles with specified ratio of required atoms of metals and size of nanoparticles, with even distribution on carrier surface, high efficiency and high catalytic activity in process of thin-walled CNT production, having up to 5 layers in walls; with narrow distribution along diametre in the range of 1-5 nm, with high yield.
