Embodiment 1

[0013] Accurately weigh 0.01 mol of bismuth nitrate and grind it finely, then add 0.01 mol of ammonium phosphate and grind it quickly. As the grinding progresses, the mixture changes from white paste to white fine powder. Continue grinding for 40 minutes to ensure that the reaction is fully carried out. The product Wash with water and ethanol to obtain bismuth phosphate nanoparticles.

Embodiment 2

[0015] Accurately weigh 0.01 mol of bismuth nitrate and grind it finely, then add 0.01 mol of sodium phosphate and grind it quickly. As the grinding progresses, the mixture changes from white paste to white fine powder. Continue grinding for 40 minutes to ensure that the reaction is fully carried out, and the product Wash with water and ethanol to obtain bismuth phosphate nanoparticles.

Embodiment 3

[0017] Accurately weigh 0.01 mol of bismuth nitrate and grind it finely, then add 0.01 mol of potassium phosphate and grind it quickly. As the grinding progresses, the mixture changes from white paste to white fine powder. Continue grinding for 40 minutes to ensure that the reaction is fully carried out, and the product Wash with water and ethanol to obtain bismuth phosphate nanoparticles.

Abstract

The invention aims to provide a method for synthesizing bismuth phosphate nano particles by a room-temperature solid-phase chemical method. According to the method, cheap raw materials, namely solid bismuth salt and solid phosphate, are used as reactants, a simple operation process is adopted, and solid-phase direct chemical reaction is performed at room temperature to synthesize the bismuth phosphate nano particles. The method for preparing the bismuth phosphate nano particles, provided by the invention, has the characteristics of low cost, simplicity and good convenience in operation, short time and easiness in realization of mass production, and thus has an extremely wide application prospect.

Description

technical field [0001] The invention relates to a method for synthesizing bismuth phosphate nanoparticles by a solid phase chemical method at room temperature. Background technique [0002] Bismuth phosphate (BiPO 4 ) There are three crystal forms: monoclinic phase, monoclinic phase monazite structure and hexagonal phase structure. Among the three crystal forms, the cation Bi 3+ Form an eight-coordinated structure with oxygen atoms, P 5+ Four-coordinated with oxygen atoms, Bi and P atoms form an oxygen polyhedral spacer arrangement, and the ratio is 1:1. According to the report of Slater et al., BiPO 4 Different crystal phases can be transformed into each other, hexagonal phase structure BiPO 4 at 300 o Above C can be converted into BiPO with monazite structure 4 , the monazite-structured BiPO 4 at 600 o Above C can be converted into monoclinic BiPO 4 , while the monoclinic BiPO 4 It will slowly transform into BiPO with monazite structure at room temperature 4 . ...
