摘要：

In this work, molybdenum disulfide-titanium dioxide (MoS2-TiO2) nanohybrids were decorated on polyacrylonitrile (PAN) electrospun membrane to fabricate a highly efficient and recyclable 3D composite for photocatalytic degradation of organic pollutants. It was found that the high surface area of MoS2 nanosheets facilitated the formation of TiO2 nanotubes, which further promoted the exfoliation of MoS2 nanosheets. In addition, the matched band gaps between MoS2 nanosheets and TiO2 nanotubes brought MoS2-TiO2@PAN membrane excellent photocatalytic degradation performance of five organic dyes. The best degradation efficiency of the as-prepared MoS2-TiO2@PAN membrane was 97.73%. Based on these results, we presented the photocatalytic degradation mechanism of MoS2-TiO2@PAN membrane. Our strategy for fabricating efficient and recyclable 3D MoS2-TiO2@PAN membrane is facile, cost-efficient and eco-friendly, which will be a promising method for the photocatalytic degradation of organic dyes.
