Problems solved by technology

However, the existing electrospinning technology can often only produce solid nanofibers rather than nanotubular materials (see: J.Phys.Chem.C2011, 115, 362), such as CN101905974, CN102251305
[0004] In addition, CN103334179 also reported a method for preparing hollow structure indium oxide nanofibers. This method uses polyvinylidene fluoride nanofibers as a template, and the hollow structure indium oxide nanofibers are obtained through a sintering process. The defect of this method is that the process is complicated It is cumbersome, and it is not easy to control the wall thickness of the nanotube structure
[0005] Currently, the electrospinning technique is used to directly prepare In 2 o 3 / ZnO heterostructure nanotubes, no related reports

Abstract

The invention relates to an In2O3 / ZnO heterostructure nanotube as well as a preparation method and application of the In2O3 / ZnO heterostructure nanotube. The nanotube is formed by freely distributing In2O3 nano particles and ZnO nano particles, wherein the granularity of each ZnO nano particle and each In2O3 nano particle is respectively 15nm to 50nm and 10nm to 15nm; the inner diameter of the nanotube is 300nm to 340nm, the outer diameter is 360nm to 400nm, and the wall thickness is 15nm to 30nm. The In2O3 / ZnO heterostructure nanotube is in a hollow tubular structure, the photocatalytic activity is better compared with a single In2O3 or ZnO nanotube, the catalytic degradation rate of methyl orange in 2h can reach up to 46.6 percent by simuilating the ration of sunshine. The preparation method is simple in procedure and low in cost, and the excellent photocatalytic nature of the heterostructure nano-meter material can be highlighted.
