Abstract

The invention belongs to the technical field of synthesis of photoelectric semiconductor nano materials, and relates to an inorganic-organic hybrid material synthesis method, in particular to a method for synthesizing nano flower-shaped spherical In2Se3 diethylenetriamine (DETA) hybrid material by means of solvothermal. The method includes: using indium salt and selenium powder as reactants, using diethylenetriamine (DETA) and ethylene glycol (EG) as solvents, reacting in a reaction kettle with a polytetrafluoroethylene lining through solvothermal, washing, separating, and performing vacuum drying to obtain the hybrid material. Deducing on a growing mechanism, the method is suitable for synthesis of other inorganic-organic hybrid materials. The prepared nano flower-shaped spherical In2Se3(DETA) consists of a large-area three-dimensional flower-shaped structure, each flower is 2-3 micrometers in diameter and formed by rectangular nano sheets which are radiated around through one point, the nano sheets are smooth in surface and about 30nm in thickness, and the flower-shaped structure is free of agglomeration, fine in dispersibility and high in crystallinity. The method for synthesizing nano flower-shaped spherical In2Se3(DETA) hybrid material by means of solvothermal is environment-friendly, simple in operation, high in controllability, low in cost, high in crystallinity of obtained products, and high in yield.
