CdSNPs@NPAN‐rGO‐PAN electrospinning film with enhanced photocatalytic activity via adjusting the fiber dimension

Abstract In the paper, we report that CdSNPs@NPAN‐PAN and CdSNPs@NPAN‐rGO‐PAN composite photocatalysts were prepared by in situ growing CdS nanoparticles (CdSNPs) and N‐polyaniline (NPAN) on electrospinning films. The largest specific surface area of a fiber was made by adjusting the fiber diameter, and the photocurrent response and photodegradation of rhodamine B (RhB) experiments showed a more prominent current response and photocatalytic capacity for the CdSNPs@NPAN‐rGO‐PAN composite photocatalysts in contrast to the pure CdSNPs and CdSNPs@NPAN‐PAN photocatalysts. The nitrogen atoms on NPAN have hydrophilicity, and reduced graphene oxide (rGO) has large specific surface and high‐speed electron conductivity characteristics, which are the main factors for improving the catalytic performance. In addition, various other characterization methods had proven that CdSNPs@NPAN‐rGO‐PAN catalyst has better photocatalytic performance, and the feasible photocatalytic mechanism and cooperative effects were further analyzed in detail.
