Embodiment Construction
[0036] In order to make the content of the present invention easier to understand, the technical solutions of the present invention will be further described below in conjunction with specific embodiments, but the present invention is not limited thereto.
[0037] with C 3 N 4 Step-by-step photocatalytic preparation of AgTPPS for photocatalysts 4 / AgNPs / ng-C 3 N 4 The method for composite material, its concrete steps are:
[0038] 1) Add 30 mg ng-C 3 N 4 powder and 0.051 g AgNO 3 The solid was added to a 3:1 mixed solution of 20 ml ultrapure water and isopropanol, where isopropanol was used as a photogenerated hole capture agent. After ultrasonic treatment for 30 min, it was irradiated with ultraviolet-visible light for the first time for 60 min under the protection of nitrogen and stirring at room temperature at 800 rpm. 3 N 4 Photocatalytic reduction reaction for photocatalysts to form ng-C loaded with silver nanoparticles 3 N 4 suspension;
[0039] 2) Centrifuge...
