Embodiment 1

[0043] A preparation of CuSbS by microwave liquid phase method 2 A method for nanoparticles comprising the steps of:

[0044] Weigh 0.001mol copper nitrate trihydrate, 0.002mol antimony trichloride, 0.003mol thiourea, and 30mg / mL polyvinylpyrrolidone and dissolve them in 50mL of ethylene glycol in turn, and prepare a precursor solution after it is completely dissolved to adjust the pH= 5. Using the microwave method, the precursor solution was irradiated with microwaves, the microwave power was 400W, the microwave time was 4min, and then the microwave power was adjusted to 240W, and the microwave time was 6min to prepare CuSbS 2 black solution. The black solution was washed three times with ultrapure water and ethanol, and the CuSbS 2 The black solution was centrifuged to obtain CuSbS 2 nanoparticles. Then the CuSbS 2 Nanoparticles placed in 0.2mol / L NaS 2 CuSbS in solution with ultrasonic vibration for 20 min and magnetic stirring at 25 °C for 60 min 2 nanoparticles. ...

Embodiment 2

[0048] Weigh 0.001mol cupric chloride, 0.0011mol antimony acetate, 0.0042mol thioacetamide, 24mg / mL hexadecyltrimethylammonium bromide and dissolve them in polyethylene glycol-200 and ethylene glycol at a ratio of 5:5 50mL solution mixed in the proportion of the mixture, after it was completely dissolved, it was prepared as a precursor solution and hydrochloric acid was added to adjust the pH=2. The precursor solution was heated by microwave with a microwave power of 600W and a microwave time of 6min, then a microwave power of 160W and a microwave time of 4min to prepare CuSbS 2 black solution. The black solution was washed three times with ultrapure water and ethanol, and the CuSbS 2 CuSbS was separated from the black solution by centrifugation 2 nanoparticles. Then the CuSbS 2 Nanoparticles placed in 0.36mol / L NaS 2 CuSbS in solution with ultrasonic vibration for 20 min and magnetic stirring at 60 °C for 30 min 2 nanoparticles. The cleaned CuSbS 2 Nanoparticles dry. ...

Embodiment 3

[0050] Weigh 0.001mol copper chloride, 0.0025mol antimony nitrate, 0.0175mol L-cysteine, 12mg / mL sodium dodecylbenzenesulfonate and dissolve them in 50mL glycerol in turn, and prepare Precursor solution and adding hydrochloric acid to adjust pH=1. Microwave the precursor solution by microwave heating, the microwave power is 200W, the microwave time is 2min, and then the microwave power is adjusted to 480W, and the microwave time is 12min to prepare CuSbS 2 black solution. The black solution was washed three times with ultrapure water and ethanol, and the CuSbS 2 The black solution was centrifuged to obtain CuSbS 2 nanoparticles. Then the CuSbS 2 Nanoparticles placed in 0.68mol / L NaS 2 CuSbS in solution with ultrasonic vibration for 30 min and magnetic stirring at 40 °C for 20 min 2 nanoparticles. The cleaned CuSbS 2 Nanoparticles dry. CuSbS 2 The morphology and photocatalytic properties of the nanoparticles are consistent with the results of Example 1.

Abstract

The invention discloses a preparing method and application of a CuSbS2 nanoparticle. The particle is an agglomerate with a regular square rod-shaped structure. The preparing method comprises the stepsthat copper salt, antimonic salt and a sulfocompound are dissolved in a solvent, and then a precursor solution is prepared after the materials are fully dissolved; a microwave method is adopted for preparing the CuSbS2 nanoparticle; a Na2S solution is added into the obtained CuSbS2 nanoparticle for removing impurity phases. According to the CuSbS2 nanoparticle and the preparing method and application thereof, by regulating preparing technologies and parameters, the purpose of regulating the crystal appearance is achieved, then the ideal crystal surface appearance is prepared, the photocatalytic performance of the CuSbS2 nanoparticle is improved, and the CuSbS2 nanoparticle can increase the degradation rate of rhodamine B under 7 hours of illumination by an xenon lamp of 500 W to 96% from19%.

Description

technical field [0001] The present invention relates to a kind of solar energy, photocatalytic material and preparation method, application, specifically relate to a kind of CuSbS 2 Nanoparticles and their preparation methods and applications. Background technique [0002] With the advancement of modern science and technology, the serious pollution of the environment caused by traditional fossil energy and its increasing scarcity have brought great challenges to human survival and development. Therefore, countries all over the world are seeking an alternative renewable energy, forcing people to look for a renewable and pollution-free energy. As a widely distributed, energy-storage, and environmentally friendly energy source, solar energy is considered an ideal alternative energy source. Therefore, solar cells are widely concerned and used. At present, silicon solar cells are basically used in the market, but the manufacturing process of crystalline silicon cells is highly...
