Abstract

The invention belongs to the technical field of preparation of micro-nanometer materials, and particularly relates to a one-step method for preparing one-dimensional Sb203 micro-nanometer powder and composite-morphological Sb203 micro-nanometer powder. Liquor with SbCl3 soluble in ethanol is added into alkali liquor to realize reaction, and one-dimensional Sb203 micro-nanometer powder and composite-morphological Sb203 micro-nanometer powder are obtained by means of filtering and drying. The method is simple, time-saving and labor-saving, is low in cost and environmental pollution, and saves energy, optional additives are omitted in a preparation procedure, and the one-step method has high industrial application potential.

Description

technical field [0001] The invention belongs to the technical field of preparation of micro-nano materials, in particular to a one-dimensional and composite morphology Sb prepared by a one-step method. 2 o 3 The method of micronano powder. Background technique [0002] Because one-dimensional and its composite structure micro-nano materials have some unique mechanical, optical, electromagnetic and other properties, they have become a hot spot in the field of materials science. At present, the methods for preparing one-dimensional and its composite structure micro-nano powder mainly include vapor deposition method, water / solvothermal method, template method and ultrasonic method. However, the preparation process of the above method is relatively complicated, the reaction time is long, the energy waste is serious, and a large amount of additives need to be added, which pollutes the environment and seriously restricts the application research of micro-nano materials. So far,...
