[0039] (2) In terms of preparation method, while utilizing the natural characteristics of biological templates, this method realizes the direct ingenious compounding of two materials on the biological template platform through two consecutive sol-gel impregnation methods, which not only overcomes the sol-gel The method is complicated to operate and needs to accurately control the shortcomings of various experimental parameters, and it also omits the tedious experimental steps in the composite material preparation process.

[0040] (3) In terms of material performance, since the sol-gel impregnation reaction occurs continuously on the surface of the biological template, it promotes the efficient combination of the two materials and the uniform distribution of the grains during the composite process, which contributes to the stability and stability of the composite material. A substantial boost in performance. The hollow composite micro-nano material prepared by the method has a...

Abstract

The invention discloses a CuO-TiO2 composite micro tube and a preparation method and application thereof. The mole ratio of CuO to TiO2 in the CuO-TiO2 composite micro tube is 1:(1-5), the diameter ofthe CuO-TiO2 composite micro tube is 15-22 microns, and the wall thickness of the CuO-TiO2 composite micro tube is 1-3 microns; the specific surface area of the CuO-TiO2 composite micro tube is 120-140 m<2> / g. In terms of material performance, since a sol-gel impregnation reaction continuously occurs on the surface of a biological template, high-efficiency bonding and uniform distribution of crystal grains in the compounding process of the two materials are promoted, and the full improvement of the stability and performance of a composite material is facilitated. The hollow composite micro / nano material prepared by the method is stable in structure and capable of keeping a good hollow structure, has the advantages of low density, high specific surface area and the like, and has excellentapplication effects.

Description

technical field [0001] The invention belongs to the field of inorganic composite materials, in particular to a CuO-TiO 2 Composite microtube, preparation method and application thereof. Background technique [0002] Among many micro-nano composite materials, hollow composite materials have the characteristics of low density, large specific surface area, and can accommodate guest molecules, and are widely used in environmental protection, biomedicine, electronics and other fields. The template method is the most important and widely used method for preparing hollow composite materials. It uses monodisperse polymer particles, inorganic particles, emulsion droplets, vesicles, bubbles, etc. Coating one or more layers of material, and then removing the template by calcination or solvent extraction to obtain a hollow material. The template method has the characteristics of simple preparation process, high repetition rate and good predictability, and has been widely used now. ...
