Problems solved by technology

The preparation methods of conventional composite structures often require multi-step cumbersome operations, and multi-step operations often lead to the reduction of material properties and increase the preparation cost. Therefore, it is necessary to find a synthesis method that is simple to operate and low in cost.

Abstract

The invention discloses a one-step synthetic method of a nano-particles and nanorod hybridization structure. The one-step synthetic method of the nano-particles and nanorod hybridization structure comprises the following steps: sequentially dissolving reactant precursor polyethylenimine, zinc nitrate, nitric acid, and hexamethylenetetramine in deionized water, and then conducting the solution in hydrothermal reaction, and eventually acquiring the nano-particles and the nano-particles and nanorod hybridization structure. The one-step synthetic method of the nano-particles and nanorod hybridization structure has the advantages of being simple to operate, low in cost and non-toxic of the precursor material, and controllable in sizes of the nanorod and nano-particles. Materials with a nanometer function can be applied to multiple fields of solar cells, infrared glowing and the like.
