| abstract |
The invention discloses a PDI loaded biochar photocatalyst as well as a preparation method and a use method thereof, wherein the photocatalyst is prepared from the following raw material components: PDI, biochar and acid in a mass ratio of 1-45:1: 3000-7000. The method takes perylene-3, 4,9, 10-tetracarboxylic dianhydride, beta-alanine, imidazole and biochar as raw materials, obtains PDI by adopting an organic synthesis method, obtains the photocatalyst by synchronous acidification, and provides a using method of the photocatalyst. |
