Example Embodiment

[0016] Example 1

[0017] Weigh 0.026g of g-C 3 N 4 The powder was added to 35 ml of deionized water, sonicated for 30 minutes, then 0.595 g of silver nitrate was weighed and dissolved in the above dispersion liquid, and the stirring was continued for 4 hours. Subsequently, 35 ml of KCl aqueous solution with a concentration of 0.1 M was slowly added dropwise to the above mixed solution, and the reaction was continued for 24 hours. The product was washed and dried to obtain the corresponding AgClg-C 3 N 4 Composite photocatalytic materials. Test the AgClg-C 3 N 4 -5% for the photocatalytic properties of methyl orange such as figure 1 shown.

Example Embodiment

[0018] Example 2

[0019] Weigh 0.056g of g-C 3 N 4 The powder was added to 9 ml of deionized water, sonicated for 1 hour, and then 0.459 g of silver nitrate was weighed and dissolved in the above dispersion liquid, and the stirring was continued for 4 hours. Subsequently, 9 ml of KBr aqueous solution with a concentration of 0.3M was slowly added dropwise to the above mixed solution, and the reaction was continued for 18 hours. The product was washed and dried to obtain the corresponding AgBrg-C 3 N 4 -10% composite photocatalytic material.

Example Embodiment

[0020] Example 3

[0021] Weigh 0.129g of g-C 3 N 4 The powder was added to 22 ml of deionized water, sonicated for 1 hour, then 0.374 g of silver nitrate was weighed and dissolved in the above dispersion, and the stirring was continued for 3 hours. Subsequently, 22 ml of KI aqueous solution with a concentration of 0.1 M was slowly added dropwise to the above mixed solution, and the reaction was continued for 24 hours. The product was washed and dried to obtain the corresponding AgIg-C 3 N 4 -20% composite photocatalytic material.

Abstract

The invention discloses a method for preparing an AgX@g-C3N4 composite photocatalytic material. The method comprises the steps of: firstly treating g-C3N4 with a laminated structure in a silver salt solution under the action of ultrasound so that silver ions are loaded on the surface of the g-C3N4; and adding a halide salt solution to carry out precipitation reaction on the silver ions and halide ions, so as to obtain the AgX@g-C3N4 composite material. The method is low in cost, and simple and easy in preparation process and the visible photocatalytic activity of products is high.

Description

technical field [0001] The present invention relates to a kind of g-C that utilizes halide ion and has lamellar structure 3 N 4 Precipitation reaction between surface-supported silver ions to support silver halide on g-C 3 N 4 AgXg-C 3 N 4 A method for composite photocatalytic materials, specifically involving silver ions in g-C 3 N 4 Surface loading, loading of halide ions and other processes. Background technique [0002] Energy crisis and environmental pollution are major problems faced by mankind in the new century, and photocatalytic technology is of great significance in alleviating or even solving these two problems. As the core of photocatalytic technology, the exploration of photocatalyst becomes the key. [0003] Due to its photosensitivity, silver halides tend to have visible-light responsive properties, however, precisely because of photosensitivity, pure silver halides are often unstable and difficult to use as stable (visible) photocatalysts without othe...
