The invention discloses a composite photocatalyst with excellent catalytic performance. The composite photocatalyst has a 3D structure formed by cobalt-embedded nitrogen-rich porous carbon material and self-assembled carboxyl-containing peryleneimide through π-π interaction and hydrogen bonding. /1D heterostructure; the mass ratio of the cobalt-embedded nitrogen-rich porous carbon material to the self-assembled carboxyl-containing peryleneimide is 1:0.1-10. Compared with the self-assembled carboxyl-containing peryleneimide in the prior art, the present invention exhibits more excellent photocatalytic performance and recycling ability in terms of degrading pollutants and killing pathogenic bacteria, and the preparation method is green, safe, and safe. The raw material is easy to obtain, the process is simple, and has high application prospect and practical value. |
