Carbon nano bottle containing nickel nano particles and method for preparing carbon nano bottle

Abstract

The invention discloses a carbon nano bottle containing nickel nano particles and a method for preparing the carbon nano bottle. The carbon nano bottle contains the nickel nano particles with diameters of 4-6nm. The wall thickness of the carbon nano bottle is 8-16nm, the length of the carbon nano bottle is 420-440nm, and diameter of the carbon nano bottle is 65-115nm. The method for preparing the carbon nano bottle comprises the following steps of: anodizing an aluminium sheet twice under different anodizing voltages to obtain a bottle-shaped porous alumina template; putting the bottle-shaped porous alumina template into an atmosphere of the mixture of acetylene and argon, and treating to obtain a nano-porous alumina template with a carbon nano bottle on the porous wall thereof; putting the nano-porous alumina template with the carbon nano bottle on the porous wall thereof into a plasma cleaning device, cleaning and soaking in a nickel nitrate solution in sequence to obtain a nano-porous alumina template with the carbon nano bottle and nickel nitrate on the porous wall thereof in sequence; and putting the nano-porous alumina template with the carbon nano bottle and the nickel nitrate on the porous wall thereof into the atmosphere of the mixture of hydrogen and argon and the atmosphere of the mixture of acetylene and argon in sequence, treating and putting the treated nano-porous alumina template into a strong alkali solution to remove the alumina template by corroding to obtain the target product. The carbon nano bottle disclosed by the invention has a wide application prospect in the aspects of medicament transport, isolated chemical reaction, self-healing anti-corrosion coatings and the like.

Description

technical field [0001] The invention relates to a carbon nano bottle and a preparation method thereof, in particular to a carbon nano bottle containing nickel nanoparticles and a preparation method thereof. Background technique [0002] With low density, high specific surface area, high mechanical strength, excellent electrical properties and good physical and chemical stability, carbon nanotubes are generally considered to be an excellent carrier for loading drugs, quantum dots, magnetic particles and Catalyst etc. In recent years, people have made some attempts and efforts to obtain carbon nanotubes, such as a "method for modifying carbon nanotubes with nickel nanoparticles" disclosed in Chinese invention patent application publication CN101549865A on October 7, 2009. The published specification of this invention patent application describes that nickel nanoparticles are uniformly supported on the surface of carbon nanotubes using a chemical reduction method. However, bo...

AI Technical Summary

Problems solved by technology

However, both the carbon nanotubes with nickel nanoparticles on the surface and their preparation methods have shortcomings. First, carbon nanotubes are through tubes with two ends open, and it is difficult to effectively store the substances to be carried in the tubes. Secondly, although the carbon nanotubes decorated with nickel nanoparticles have strong magnetic responsiveness, it is very easy to have undesirable interactions with the substances to be carried and other substances because the nickel nanoparticles are loaded on the surface of the carbon nanotubes. chemical reaction; again, the preparation method cannot obtain carbon nanobottles coated with nickel nanoparticles
