Abstract

The invention discloses a preparation method for cadmium molybdate porous spheres. The preparation method comprises the following steps of mixing a cadmium chloride solution and a sodium acetate solution to prepare a cadmium acetate precipitate solution, mixing the cadmium acetate precipitate solution and a sodium molybdate solution, loading the mixed solution in a reaction kettle, preserving heat for 2 to 12 hours at 110 to 200 DEG C, performing hydrothermal treatment, repeatedly washing a reaction product by using distilled water after the reaction product is unloaded from the reaction kettle, and filtering and drying the reaction product to obtain the cadmium molybdate porous spheres. The preparation method has the advantages of simple process, no organic surfactants, no pollution, easiness in industrial production, high crystallinity, high purity, capability of effectively controlling the morphology of cadmium molybdate crystals, and the like.

Description

technical field [0001] The invention relates to a preparation method of cadmium molybdate, in particular to a preparation method of cadmium molybdate porous balls. Background technique [0002] Cadmium molybdate (CdMoO 4 ) has a scheelite structure. In this structure, the molybdenum atom is in the center of the tetrahedron. The luminescent performance of cadmium molybdate is mainly due to the transfer and transition of electrons in the molybdate radical. Therefore, it is used in photoluminescence, photocatalytic materials, optical fibers, Scintillator detectors, laser materials, magnetic materials, sensors and many other fields have broad application prospects, so they have become one of the inorganic materials that have been studied in recent years. [0003] It is well known that the photoluminescent properties of solids are related to the size, morphology and microstructure of solid particles, and the properties of nanomaterials also depend on factors such as the morpholo...
