Abstract

The invention relates to a preparation method of a hollow sulfide nanometer material and the hollow sulfide nanometer material prepared through the method. According to the method of the synthesized hollow sulfide nanometer material, reaction temperature is low, reaction time is short, and the obtained product has the advantage of being good in monodispersion. The prepared hollow sulfide nanometer material has a large specific surface area, uniform morphology and many chemical active sites, and the hollow degree of the spherical nanometer material can be well controlled according to the reaction time.

Description

technical field [0001] The invention relates to the field of chemical material preparation, in particular to a method for preparing hollow sulfide nanomaterials. Background technique [0002] Hollow nanomaterials have lower density, larger specific surface area, and more chemically active sites, so it is of great significance to find a way to synthesize hollow nanomaterials with specific properties. Although many efforts have been made to synthesize a wide variety of hollow nanomaterials, constructing a simple and convenient method remains a thorny issue. [0003] Bryan et al. reported that hollow chalcogenide nanomaterials exhibit excellent optical, electrochemical and catalytic properties due to their large specific surface area and high chemically active sites (BryanT.Yonemoto, GregoryS.Hutchings, and Feng Jiao, A General Synthetic Approach for Ordered Mesoporous Metal Sulfides. Journal of the American Chemical Society, 2014, 136, 8895-8898). For example, hollow ZnS has...
