Porous polyacrylonitrile (P-PAN) nanofibers containing a conjugated microporous polymer (CMP) with photocatalytic ability were electrospun to obtain a reusable photocatalyst composite. P-PAN nanofiber was used as a robust supporting matrix for the CMP and could prevent undesirable CMP leakage during use. To provide porous nanofibers, poly (vinyl pyrrolidone) was used as a sacrificial porogen, allowing facile access of dye molecules to degrade, or of the organic reagent to react. When exposed to visible light, the photocatalyst composite degraded rhodamine B (RhB) by more than 90% in 150 min. In addition, more than 85% of the RhB degradation was maintained even after 10 cycles of reuse. The nanofibrous photocatalyst was able to oxidize various benzylamine derivatives to convert to N-benzylbenzaldimines under visible light. It could also be reused several times for repeated photocatalytic organic reaction after simple washing.

将包含具有光催化能力的共轭微孔聚合物（CMP）的多孔聚丙烯腈（P-PAN）纳米纤维进行静电纺丝，以获得可重复使用的光催化剂复合材料。P-PAN纳米纤维被用作CMP的坚固支撑基质，并可以防止在使用过程中CMP泄漏。为了提供多孔纳米纤维，将聚乙烯吡咯烷酮用作牺牲性致孔剂，使染料分子易于降解或有机试剂发生反应。当暴露于可见光下时，光催化剂复合物在150分钟内将罗丹明B（RhB）降解了90％以上。此外，即使重复使用10个循环后，RhB的降解率仍可维持在85％以上。纳米纤维光催化剂能够氧化各种苄胺衍生物以转化为N-苄基苯二胺在可见光下。简单洗涤后，也可以重复使用几次以重复进行光催化有机反应。
