Problems solved by technology

The Yang Jinfei research group of Nanjing Normal University introduced a method for preparing aluminum hypophosphite in CN103145110A and CN102786041A respectively, but hypophosphorous acid is thermally decomposed to produce highly toxic phosphine gas, and hypophosphite is not easy to control, resulting in more impurities in the product

Embodiment 1

[0028] Dissolve 0.08mol aluminum nitrate and 1.21g urea in 80ml of deionized water, stir vigorously for 20min, then dissolve 0.08mol trisodium phosphate in the above solution, continue stirring for 30min, then transfer the solution to 100ml of polytetrafluoroethylene In the lined stainless steel hydrothermal reaction kettle, seal it, set the reaction temperature to 150°C, and close the reaction after 35 hours of reaction. When the reaction kettle is cooled to room temperature, use a vacuum filter to separate the white precipitate from the solution, and then remove the white The precipitate was washed with ethanol and distilled water. The obtained samples were dried at 60 °C for 24 h. Gained sample is done X-ray diffraction analysis (results such as figure 1 shown) and transmission electron microscope analysis (results are shown in figure 2 shown). This embodiment makes nano-rod AlPO 4 -15 powder.

[0029] from figure 1 It can be seen that the XRD pattern of the sample, ...

Embodiment 2

[0032] Dissolve 0.16mol aluminum nitrate and 2.0g urea in 80ml of deionized water, stir vigorously for 20min, then dissolve 0.16mol trisodium phosphate in the above solution, continue stirring for 30min, then transfer the solution to 100ml of polytetrafluoroethylene In the lined stainless steel hydrothermal reaction kettle, seal it, set the reaction temperature to 150°C, and close the reaction after 30 hours of reaction. When the reaction kettle is cooled to room temperature, use a vacuum filter to separate the white precipitate from the solution, and then remove the white The precipitate was washed with ethanol and distilled water. The obtained samples were dried at 60 °C for 24 h. The obtained samples were analyzed by transmission electron microscope (results such as image 3 shown).

Embodiment 3

[0034] Dissolve 0.16mol aluminum nitrate and 2.0g urea in 80ml of deionized water, stir vigorously for 20min, then dissolve 0.16mol trisodium phosphate in the above solution, continue stirring for 30min, then transfer the solution to 100ml of polytetrafluoroethylene In the lined stainless steel hydrothermal reaction kettle, seal it, set the reaction temperature to 150°C, and close the reaction after 50 hours of reaction. When the reaction kettle is cooled to room temperature, use a vacuum filter to separate the white precipitate from the solution, and then remove the white The precipitate was washed with ethanol and distilled water. The obtained samples were dried at 60 °C for 24 h. The obtained samples were analyzed by transmission electron microscope (results such as Figure 4 shown).

[0035] from Figure 4 It can be seen that the reaction time has a certain influence on the rod-shaped growth. When the reaction time is short, the obtained particles are tiny. As the react...

Abstract

The invention discloses a synthesis method of nanorod-shaped AlPO4-15, and belongs to the field of nanomaterials. The method comprises the following steps: 1, dissolving an aluminum salt in water to prepare an aluminum salt solution with the concentration of 0.8-3mol / L; 2, adding urea to the aluminum salt solution according to a molar ratio of the aluminum salt to urea of 4:1-15:1, and stirring for 10-60min; 3, adding phosphate to a solution obtained in step 2 according to a molar ratio of Al:P of 1:1, and stirring for 10-60min; and 4, transferring a solution obtained in step 3 to a hydrothermal reaction kettle, reacting at 130-160DEG C for 30-72h, filtering after the reaction ends, washing the obtained filter cake, and drying to obtain nanorod-shaped AlPO4-15 powder. AlPO4-15 nanorods are formed through self-assembling under hydrothermal synthesis conditions by changing the content of urea, prolonging the reaction time and adjusting the reaction temperature.

Description

technical field [0001] The invention relates to the technical field of nanomaterials, in particular to a nanorod-shaped AlPO 4 Synthesis of -15. Background technique [0002] Nanorod-structured substances have attracted researchers' interest in recent years due to their potential applications in science and technology. Nanorods represent a series of spatially one-dimensional substances and exhibit very important photochemical, photophysical and electron transfer properties. These are different from other structural substances. [0003] Phosphate because of its special structural unit MPO 4 got a lot of attention. In this structural unit, M is a trivalent metal ion, which can add different kinds of framework structures. The structural form of these phosphates has been deduced by Bellitto Carlo et al., in a distorted octahedral coordination, with each metal atom surrounded by six oxygen atoms, forming four bridging groups, one terminal and the other from water. Molecules...
