Embodiment 1

[0033] In this example, a polyaniline / g-C 3 N 4 The preparation method of @glucose composite material comprises the following steps:

[0034] (1) g-C 3 N 4 Preparation of @glucose composite material:

[0035] a. Weigh 10g of dicyandiamide powder as a raw material, place it in a porcelain crucible with a volume of 100ml, and place it in a muffle furnace at 5°C min -1 The heating rate was raised to the reaction heating temperature of 550 °C, and then kept at the reaction temperature for 4 hours, and then cooled to room temperature to obtain yellow g-C 3 N 4 Material;

[0036] b. Weigh 0.5g of g-C prepared in the step a 3 N 4 material, the g-c 3 N 4 The material was added to 40 mL of glucose solution with a molar concentration of 0.3M to form g-C 3 N 4 and glucose, and ultrasonically mix the mixture for 6 hours to form a suspension, then transfer the suspension to a high-pressure reactor with a volume of 50mL, and heat it at 180°C for 10 hours, and centrifuge the reac...

Abstract

The invention discloses a polyaniline / g-C3N4-coated glucose composite material preparation method. The method comprises the following steps: 1) placing dicyandiamide in a muffle furnace to prepare g-C3N4; 2) adding the prepared g-C3N4 in a glucose solution for ultrasonic wave, transferring a fluid suspension to a high-pressure reaction vessel, heating the material at the temperature being no lowerthan 180 DEG C for at least 10 hours, and washing and drying the material to obtain the g-C3N4-coated glucose composite material; and 3) mixing the g-C3N4-coated glucose composite material obtained in the step 2) and chloroform and aniline, and performing ultrasonic wave treatment to obtain a solution A; dissolving perchloric acid and ammonium persulfate in the deionized water to obtain a solution B, rapidly mixing the solution A and the solution B, and stirring a mixed solution for at least 20 hours; removing a water phase and purifying the material through dialysis, and drying the materialat the temperature being no lower than 70 DEG C to obtain the polyaniline / g-C3N4-coated glucose composite material. The prepared composite material has the advantages of tight structure connection andexcellent photocatalysis performance.

Description

technical field [0001] The present invention relates to a kind of preparation method of photocatalyst, relate in particular to a kind of modified g-C 3 N 4 The preparation method of the composite catalyst is applied in the technical field of wastewater treatment and the technical field of composite nanomaterials. Background technique [0002] With the rapid economic development, environmental pollution has become one of the hottest topics in the world. In recent years, due to the broad prospect of photocatalytic technology in the environmental remediation of organic wastewater treatment, and the inexhaustible and inexhaustible sunlight to obtain driving energy, it has received extensive attention. Due to the special semiconductor characteristics of graphite phase carbonitride, the band gap reaches 2.7ev, and it has high stability, non-toxicity, easy preparation, corrosion resistance to acid, alkali and light, easy regulation of structure and performance, and good photocata...
