Abstract

The invention provides a method of modifying g-C with glutamic acid 3 N 4 ‑Cu 2 Preparation method of O composite catalyst and its application, the method includes the following steps: obtaining a first solution, the first solution includes Cu in a dissolved state 2+ ions as well as glutamic acid; add protonated g‑C to the first solution 3 N 4 , stir, and ultrasonic to obtain a suspension; add xylitol to the suspension under stirring, adjust the pH value to 10-12, and stir to obtain a mixed solution; heat the mixed solution to 150 in a high-pressure reaction vessel -200°C, constant temperature reaction for 25-35h to obtain the reactants; separate the cooled reactants from solid and liquid, wash, and vacuum dry to obtain a solid product; heat the solid product to 150-250°C under the protection of inert gas and maintain Keep the temperature constant for 1h-3h to obtain g-C 3 N 4 ‑Cu 2 O composite catalyst. The composite catalyst has stronger visible light absorption ability, and enhanced photocatalytic performance and stability.
