Method for preparing terbium oxide assembled carbon nano tube composite material

Abstract

The invention relates to a preparation method for Tb2O3 assembled carbon nanometer tube compound material. Dissolve Tb2O3 in the aqua fortis, the preparation of Tb(NO3)3 crystal, under the room temperature, joined the carbon nano tube in the aqua fortis which included Tb(NO3 )3, supersonic disperser, 120 íµ - 140 íµ oil baths backflow 3 - 8 hours, when the backflow intermixture temperature drop to room temperature, carried on 15 - 70mol / l soluble alkali Titration, the filter diaphragm filtered, washes, dry 5 - 12 hours in 60 - 100 íµ; In the inert atmosphere, when the room temperature rise to 250 íµ, then maintains 1 - 2 hours, then elevates temperature to 400 - 700 íµ, maintains 0.5-3 hour, cools to the room temperature, then forms Tb2O3 assemblies carbon nanometer tube compound material. Advatages: simple method, good catalysis, good electricity and optical performance.

Description

technical field

[0001] The invention relates to a preparation method of a novel composite material of carbon nanotubes, in particular to a preparation method of a novel composite material of terbium trioxide assembled carbon nanotubes. Background technique

[0002] Carbon nanotubes have attracted great attention from scientists for their unique physical and chemical properties. Studies have shown that the assembly of carbon nanotubes with inorganic, organic, and biological materials will produce more excellent physical and chemical properties, such as better electrical properties, optical properties, mechanical properties, adsorption properties and wave absorption properties, etc., will have a broader At the same time, carbon nanotubes can also be used as templates to assemble nanowires and nanotubes. These nanowires and nanotubes will be important raw materials for the next generation of nanodevices. The assembled carbon nanotubes will have important applications in cataly...
