Embodiment 1

[0018] Mix equimolar tin chloride solution and calcium acetate solution, stir evenly, add ethylenediamine and sodium dihydrogen phosphate regulators, the molar ratio of the amount to tin salt is 1:1, stir for 20 min, Then a certain amount of NaOH solution was slowly added dropwise, the molar ratio of alkali to tin salt was 1:7, and transferred to a hydrothermal kettle to react for 15 hours at a reaction temperature of 100°C.

[0019] Such as figure 1 As shown, the obtained tetradecahedral calcium hydroxystannate has good morphology and regular scale.

[0020] Tetradecahedral calcium hydroxystannate and hexahedral calcium hydroxystannate were used for photocatalytic degradation of methylene blue, such as figure 2 As shown, the photodegradation effect of tetradecahedron is better than that of hexahedron.

Embodiment 2

[0022] Mix equimolar tin chloride solution and cobalt acetate solution, stir evenly, add two regulators, triethanolamine and potassium phosphate, the molar ratio of the amount to tin salt is 1:2, stir for 60 min, then slowly drop Add a certain amount of NaOH solution, the molar ratio of alkali to tin salt is 1:6, and transfer to a hydrothermal kettle to react for 20h, and the reaction temperature is 90°C.

Abstract

The invention provides tetrakaidecahedron metal hydroxystannate and a preparation method and application thereof. The molecular formula of the tetrakaidecahedron metal hydroxystannate is MSn(OH)6, wherein M is Ca, Mg, Co, Ni, Mn or Cu. The preparation method includes: mixing equal-mole tin salt solution and metal salt solution, stirring, adding regulator, stirring for 10 minutes to 3 hours, dropwisely adding alkaline solution, and transferring to a hydrothermal kettle for reaction for 5-24 hours to obtain the tetrakaidecahedron metal hydroxystannate, wherein the reaction temperature is 25-120 DEG C. The tetrakaidecahedron metal hydroxystannate is widely applicable to the technical field of photocatalysis, and the light degradation effect of tetrakaidecahedron light is better than that of hexahedron light during methylene blue degradation using photocatalysis.

Description

technical field [0001] The invention belongs to the technical field of photocatalytic materials, and in particular relates to tetradecahedral hydroxystannate and its preparation method and application. Background technique [0002] Hydroxystannate is a typical perovskite structure hydroxide, which has excellent photocatalysis, flame retardancy and smoke suppression properties, and is one of the key materials to solve energy and environmental problems. Since the morphology, size, and structure of hydroxystannate have important effects on its flame retardancy and photocatalytic properties, the controlled synthesis of hydroxystannates with different morphologies has attracted widespread attention. At present, MSn(OH) with regular hexahedral morphology 6 (M=Ca, Mg, Co, Ni, Mn, Cu) have been preliminarily studied, but tetradecahedral hydroxystannates are rarely reported. Contents of the invention [0003] Technical problem to be solved: the purpose of the present invention is...
