specific Embodiment approach 1

[0011] Embodiment 1: Accurately weigh 0.01 mole of cadmium acetate and place it in an agate mortar, add 20 mg of graphite oxide after fully pulverizing it, grind for 60 minutes and mix evenly, add 0.01 mole of thioacetamide, then mix it Grind thoroughly for 60 minutes and let stand for 3 hours to ensure complete solid phase reaction. Wash it with deionized water and absolute ethanol, filter it with suction, and dry it in a drying oven at 60°C for 2 hours to obtain the cadmium sulfide / graphite oxide composite material.

specific Embodiment approach 2

[0012] Embodiment 2: Accurately weigh 0.01 mole of cadmium chloride and place it in an agate mortar, add 20 mg of graphite oxide after it is fully ground, grind for 60 minutes and mix evenly, add 0.01 mole of thioacetamide, and then It was thoroughly ground for 60 minutes and left for 3 hours to ensure complete solid phase reaction. Wash it with deionized water and absolute ethanol, filter it with suction, and dry it in a drying oven at 60°C for 2 hours to obtain the cadmium sulfide / graphite oxide composite material.

specific Embodiment approach 3

Description

technical field [0001] The invention relates to a method for preparing a cadmium sulfide / graphite oxide composite material in a solid phase, and belongs to the field of nanometer material preparation. Background technique [0002] In recent years, nanomaterials have attracted extensive attention of researchers because of their unique physical and chemical properties. As a very important semiconductor nanomaterial, cadmium sulfide has great application prospects in the fields of semiconductor light-emitting devices, nonlinear optical materials, and photocatalysis because of its specific optical, electrical, thermal, and magnetic properties. However, due to the small size effect and surface effect of cadmium sulfide nanomaterials, it is easy to agglomerate during the preparation process, which affects its performance and practical application. Therefore, various methods have been adopted to slow down the agglomeration of CdS nanomaterials. Among them, the use of templates as...
