Abstract

The invention belongs to the technical field of synthesis for environment-friendly nanometre materials, relates to a method for synthesising inorganic and organic hybrid materials, and particularly relates to a method for synthesising In2Se3 (en) hollow nanospheres by means of hydrothermal method. The method for synthesising In2Se3 (en) hollow nanospheres by means of hydrothermal method comprises the following steps of: reacting in a reaction kettle by means of hydrothermal method by taking indium chloride and selenium powder as reactants and the mixed solution of ethanediamine (en), deionized water and hydrazine hydrate as a solvent, cooling to a room temperature and then washing by virtue of absolute ethyl alcohol, separating and then vacuum-drying, and then obtaining the In2Se3 (en) hollow nanospheres. Inference from the growth mechanism shows that the method is suitable for synthesising the inorganic and organic hybrid materials of other metal selenides. The In2Se3 (en) hollow nanospheres prepared by the method are good in dispersity, without an agglomeration phenomenon, uniform in size, 150+ / -5 nm in diameter, rough in surfaces, and formed by randomly accumulating small particles having a single-crystal structure and a lattice distance of 0.279 nm. The preparation method disclosed by the invention has the advantages of being green and environment-friendly, low in cost, simple in operation, strong in controllability, and good in the crystallinity of the obtained products.

Description

technical field [0001] The invention belongs to the technical field of synthesis of environment-friendly nano-materials, relates to a synthesis method of an inorganic-organic hybrid material, in particular to a hydrothermal method for synthesizing In 2 Se 3 (en) Nanohollow sphere method. Background technique [0002] With the development of science and technology, people's requirements for materials are getting higher and higher. Different types of materials are made into composite materials through certain processes, which can keep the advantages of the original two substances and overcome the original components. shortcomings and show some new properties. In the past few decades, studies on the synthesis, characterization and modification of inorganic-organic hybrid materials have attracted the attention of scientists. Inorganic-organic hybrid material is a homogeneous multiphase material, in which at least one phase has at least one dimension at the nanometer level, an...
