摘要/Abstract

摘要： 利用溶胶凝胶法和超临界干燥技术合成了聚酰亚胺(PI)气凝胶,并将PI气凝胶在800 ℃下进行煅烧,再以煅烧生成的含氮碳气凝胶(C(N))与PI气凝胶复合制备具有高比表面积和独特孔结构的C(N)/PI气凝胶复合材料,用于光催化降解土霉素。结果显示,相比PI气凝胶,C(N)/PI气凝胶复合材料既具有较大的比表面积,又同时含有微孔和介孔,可增加光催化过程中的活性位点和光谱利用率,在6 h内土霉素浓度降低了82%,有效地提高了土霉素的光催化降解效率。

关键词: PI气凝胶, 含氮碳气凝胶(C(N)), 光催化, 土霉素

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
