Problems solved by technology

[0004] At present, the cadmium molybdate material prepared by the hydrothermal method can usually only obtain spherical powder particles, while the octahedral cadmium molybdate crystallites synthesized by the microemulsion method are inconvenient for subsequent processing due to the addition of a large amount of organic matter.

Abstract

The invention discloses a method for preparing a cadmium molybdate nanorod. The method comprises the following steps: mixing a cadmium chloride solution and a potassium carbonate solution, and reacting to obtain a cadmium carbonate precipitate; mixing the precipitate with a sodium tungstate solution, adding the mixture into a reaction kettle, preserving the temperature to 110-150 DEG C for 2-6 hours, and performing hydrothermal treatment; naturally cooling to room temperature, adding sodium molybdate powder, preserving the temperature to 180-220 DEG C for 8-12 hours, and performing hydrothermal treatment; and naturally cooling the reaction kettle to room temperature, discharging the kettle, repeatedly washing the reaction product by using distilled water, filtering, and drying, thereby obtaining the cadmium molybdate nanorod. The preparation of the cadmium molybdate nanorod having a one-dimensional structure is realized at the first time, the preparation method has the advantages that the process flow is simple, any organic surfactant is not used and the pollution is avoided, industrial production is easily realized, and the cadmium molybdate nanorod has wide application values in the fields of photoluminescence, optical fibers and sensors.

Description

technical field [0001] The invention relates to a preparation method of a cadmium molybdate material, in particular to a preparation method of a cadmium molybdate nanorod. Background technique [0002] Cadmium molybdate (CdMoO 4 ) has a scheelite structure and is an important inorganic material. Because cadmium molybdate has superior luminescent properties and good color rendering and color changing effects, it has broad application prospects in many fields such as photocatalytic materials, scintillator detectors, magnetic materials, photoluminescence, optical fibers, laser materials, sensors, etc. Therefore, it has become a research hotspot in the field of materials in recent years. [0003] As we all know, the performance of nanomaterials depends on factors such as the shape and size of nanocrystals, and nanomaterials with new and special shapes will show unique properties, especially one-dimensional nanomaterials because of their high aspect ratio and specific surface a...
