| titleOfInvention | Preparation method and application of carbon dot/graphite-like phase carbon nitride composite photocatalyst |
| abstract | The invention discloses a preparation method and application of a carbon dot/graphite-like phase carbon nitride composite photocatalyst, which comprises the following steps: (1) preparation of carbon dots: mixing a glucose solution and an alkaline solution, carrying out ultrasonic treatment, taking the mixed solution, adding hydrochloric acid to adjust the pH value to 6-8, adding absolute ethyl alcohol under a stirring state, adding magnesium sulfate, stirring, standing, filtering to obtain a clear solution, heating the clear solution to 50-100 ℃ until the solution changes color and solids are generated, filtering the solids, and grinding the solids into powder to obtain carbon dots; (2) mixing the prepared carbon dots with melamine according to a mass ratio (0.01-5): (1-100) proportioning; then placing the mixture into a muffle furnace for calcining at the temperature of 200-700 ℃; CDs/g-C was obtained 3 N 4 A composite photocatalyst is provided. The composite photocatalyst has good up-conversion property by utilizing carbon dots, and can convert absorbed light with long wavelength into light with short wavelength, thereby greatly improving the utilization of visible light and further improving the photocatalytic activity. |
