Embodiment

[0032] Weigh 1g of CTAB and dissolve it in 480mL of water, and keep stirring evenly at 80°C, then add 3.5mL of 2mol / L sodium hydroxide solution and continue stirring until uniform, then add 4.92g of zinc acetate dihydrate and continue stirring until uniform Afterwards, lithium hydroxide was slowly added until the solution was slightly alkaline, the mixture was stirred at 80°C for 2h and the resulting mixed solution was filtered, and the filtered product was dried at 60°C in an electric blower for 24h, and then The dried powdery product was put into a crucible, and calcined in a muffle furnace at 500° C. for 4 hours to obtain an ordered mesoporous zinc oxide matrix.

[0033] Weigh 0.1417g of europium chloride, 0.3408g of erbium chloride, 0.4558g of sulfosalicylic acid and 0.8000g of the ordered mesoporous zinc oxide prepared above in a clean beaker, add an appropriate amount of deionized water and continue at room temperature Stir for 48 hours, then inject the obtained mixture ...

Abstract

The invention relates to a regular rod-shaped porous Er/Eu-ZnO composite material and a preparation method thereof, and belongs to the technical field of nanometer material preparation. A template method and a hydrothermal method are combined; CTAB is firstly used as a template agent; Zn(CH3COO)2 is used as a zinc source; pore ordered porous zinc oxide precursors are prepared; then, the hydrothermal method is used for assembling europium chloride and erbium chloride with different mass percentage into porous ZnO base bodies; the europium chloride and the erbium chloride are object ingredientsand mineralizers; under the hydrothermal conditions, induction is performed to obtain the regular rod-shaped porous Er/Eu-ZnO composite material. The prepared composite material has the regular and ordered pore passages and larger specific surface area, and has high adsorption capability on fluid. Through the observation via a scanning electron microscope, the material has the longer rod-shaped structure and the uniform appearance rule; the emission of ZnO base bodies is promoted through the mixing of rare earth ions. The material of the novel nanometer structure has important application prospects of the field of luminous materials. The method is simple; the implementation is easy; the mass production can be realized; wide application prospects are realized.

Description

technical field [0001] The invention relates to the technical field of nanomaterial preparation, in particular to a regular rod-shaped porous Er / Eu-ZnO composite material and a preparation method thereof. Background technique [0002] Mesoporous materials refer to ordered porous materials with a pore diameter between 2-50 nm and a porosity greater than 40%. According to the size of the pores, porous materials can be divided into three types: microporous materials (microporous materials, d<2nm), mesoporous materials (mesoporous materials, 2<d<50nm) and macroporous materials (macroporous materials, d>50nm). For porous nanomaterials, after the total pore volume (porosity) reaches a certain value, if the pore size is small enough, the pore size effect and surface effect will also appear, resulting in a series of different and bulk properties. Mesoporous materials are classified according to their chemical composition, and porous materials can be divided into two maj...
