Preparation method of multiwalled carbon nanotubes derived from thiacalixarene 16-nucleus molecular clusters

Abstract

The invention discloses a preparation method of multiwalled carbon nanotubes derived from thiacalixarene 16-nucleus molecular clusters. The preparation method in the technical scheme comprises steps as follows: (1), preparation and spin coating of M16: tertiary butyl thiacalixarene H4BTC4A (0.1 mmol), NiCl2.6H2O (0.4 mmol), Dy(OAc)3.6H2O (0.3 mmol) and Na2CO3 (0.2 mmol) are mixed in DMA / CH3CN / Et3N, then a mixture is transferred into a reaction kettle and subjected to a reaction at 130 DEG C for 6 days, and a product is slowly cooled to the room temperature and named as M16; macromolecular clusters M16 are taken and put in a test tube, 10 mL of CHCl3 are added for dissolving, and a solution is dispersed on a quartz substrate with a spin-coating method and used as a catalyst precursor; (2),preparation of the carbon nanotubes with a chemical vapor deposition method. The required materials are low in cost, the preparation process is simple, the preparation cycle is short, reaction conditions are simple, and the prepared product has regular morphology, larger specific surface area, high morphology controllability and good stability and repeatability, has quite high operability and practicability and further has potential application value and quite high practicability in the fields of electro-catalytic property and the like.

Description

technical field [0001] The invention belongs to the technical field of synthesis of micro-nano materials, and in particular relates to a preparation method of multi-walled carbon nanotubes derived from thiacalixarene-based 16-nuclear molecular clusters. Background technique [0002] As a one-dimensional nanomaterial, carbon nanotubes are light in weight, perfectly connected in a hexagonal structure, and have many unusual mechanical, electrical, and chemical properties. In recent years, with the in-depth research of carbon nanotubes and nanomaterials, their broad application prospects are constantly showing. Carbon nanotubes can be regarded as graphene sheets rolled up, so according to the number of layers of graphene sheets, they can be divided into: single-walled carbon nanotubes (or single-walled carbon nanotubes, Single-walled Carbon nanotubes, SWCNTs) and Multi-walled carbon nanotubes (or multilayer carbon nanotubes, Multi-walled Carbon nanotubes, MWCNTs). Carbon nanot...
