Abstract: Polyimide(PI)aerogel was prepared by sol-gel method and ethanol super-critical technology. Then PI aerogel was calcined to be N-doped carbon aerogel(C(N))at 800 ℃. Furthermore, the obtained C(N)was coupled with PI aerogel. C(N)/PI aerogel photocatalyst was used to degrade OTC. The photocatalytic performance demonstrated that OTC had been degraded 82% in 360 min over C(N)/PI aerogel photocatalyst. Because the high surface area and pore property of C(N)/PI aerogel can provide more active sites and enhance the absorption of visible light. Thus, the photocatalytic activity was improved.

Key words: PI aerogel, N-doped carbon aerogel(C(N)), photocatalytic, oxytetracycline
