Embodiment

[0024] In a water bath at 60°C, add 1.965g of diethylenetriaminepentaacetic acid and 1.141g of antimony trichloride into 65mL of deionized water and stir for 1h; add 0.575g of antimony trichloride and stir for 0.5h to form a precursor mixture. Pour the precursor mixed solution into a 50mL polytetrafluoroethylene-lined stainless steel hydrothermal reaction kettle, conduct a hydrothermal reaction at a constant temperature of 160°C for 10h, and then centrifuge, wash and dry.

[0025] The prepared antimony phosphate was observed by electron microscope and determined by X-ray diffraction.

[0026] From figure 1 It can be seen from the figure that the antimony phosphate nanorods prepared by the present invention have a quadrangular columnar structure, the length of the rods is 35-45 μm, and the side length of the cross-section is 0.15-0.9 μm.

[0027] From figure 2 It can be seen from the figure that the diameter of the microspheres assembled with antimony phosphate nanosheets i...

Abstract

The invention relates to a simple preparation method of antimony phosphate with a mixed form structure. Diethylenetriaminepentaacetic acid and antimony trichloride are sequentially dissolved in deionized water, and fully stirred under 60°C water bath conditions; then ammonium dihydrogen phosphate is added. , stir thoroughly to form a precursor mixed solution; pour the obtained precursor mixed solution into a polytetrafluoroethylene-lined stainless steel hydrothermal reaction kettle, perform a constant temperature hydrothermal reaction at 160°C for 10 hours, centrifuge, wash and dry to obtain the product. The method of the invention is simple and easy to operate, environmentally friendly, low in cost, and the product is pure. The prepared antimony phosphate can efficiently remove organic pollutants in water, and has good application prospects. The photocatalytic activity of the antimony phosphate prepared by the present invention is significantly higher than that of commercial rutile TiO2.

Description

technical field [0001] The invention relates to the field of photocatalytic materials, in particular to a simple preparation method of antimony phosphate with mixed morphology structure. Background technique [0002] Because semiconductor materials have excellent photocatalytic properties and have good application prospects in the degradation of environmental pollutants, they have attracted people's attention, and the number of photocatalysts discovered and reported is also increasing day by day. When nanostructures are aggregated from zero-dimensional or one-dimensional into multidimensional nano-superstructures, new properties can emerge, such as optical, electrical, magnetic and catalytic properties. Nano-superstructures assembled from nano-units have become one of the current research hotspots, such as hollow spheres and three-dimensional flower-like nanostructures. Due to the excellent photocatalytic application performance of semiconductor materials, the number of pho...
