specific Embodiment approach 1

[0010] Specific embodiment 1: Accurately weigh 0.01 mole of tin tetrachloride pentahydrate and place it in an agate mortar, add 0.04 mole of sodium hydroxide after fully grinding it, then fully grind it for 60 minutes and place it for 3 hours to ensure solidification The opposite responds exactly. Wash it with deionized water and absolute ethanol, filter it with suction, and dry it in a drying oven at 60°C for 2 hours to obtain the tin dioxide monomer.

specific Embodiment approach 2

[0011] Specific embodiment 2: Accurately weigh 0.01 mole of tin tetrachloride pentahydrate and place it in an agate mortar, grind it thoroughly, add 0.005 mole of sodium lauryl sulfate, grind for 60 minutes and mix well, then add 0.04 mole of hydroxide Sodium, grind for 60 minutes and mix well, then add 0.0015 g of tourmaline, grind it thoroughly for 60 minutes and leave it for 3 hours to ensure that the solid phase reaction is complete. Wash it with deionized water and absolute ethanol, filter it with suction, and dry it in a drying oven at 60°C for 2 hours to obtain a tin dioxide-tourmaline heterojunction porous material.

Abstract

The invention relates to a method for preparing a tin dioxide-tourmaline heterojunction porous material by a solid phase process, and belongs to the field of preparation of nano materials. The methodcomprises the following steps: under the room temperature conditions, tin tetrachloride is ground, sodium dodecyl sulfate is added, mixing grinding is performed, sodium hydroxide is added, mixing grinding is performed, tourmaline is added, and mixing grinding is performed, so that the low-thermal solid phase synthesis of the tin dioxide-tourmaline heterojunction porous material is realized. The low-thermal solid-phase chemical method for preparing the tin dioxide-tourmaline heterojunction porous material disclosed by the invention has the characteristics of simple operation, no use of solvents, a high yield, low costs, a simple synthetic process and the like; and the tin dioxide-tourmaline heterojunction porous material prepared by the method has a large specific surface area, high reactivity, and potential application prospects in the fields of optoelectronic devices and photocatalysis.

Description

technical field [0001] The invention relates to a method for preparing a tin dioxide-tourmaline heterojunction porous material in solid phase, and belongs to the field of nanometer material preparation. Background technique [0002] There are tens of thousands of dyes. At present, the output of various dyes in my country has reached the level of one million tons. During the printing and dyeing process, a large amount of dyes are discharged with wastewater, which is one of the key sources of environmental pollution. Printing and dyeing wastewater has the characteristics of deep chroma, high alkalinity, high content of organic pollutants and complex components, and high biological toxicity. Traditional physical and biochemical treatment methods are not ideal for its treatment effect, and the removal rate of chroma is also poor. , and the processing time is long, it is difficult to meet the emission requirements. In 1977, Frank and Bard used titanium dioxide to degrade cyani...
