  Abstract

In this study, a dye-sensitizing graphene/TiO2(DTG) based photocatalytic composite film (TPU-DTG) was developed to address the challenging recovery of graphene photocatalyst powder from treated sewage. The composite film was created by incorporating self-made dye-sensitizing graphene/TiO2 onto an electrospun polyurethane film using electrostatic spraying technology. The structure and morphology of the composite film were analyzed using Fourier transform infrared spectroscopy (FTIR), Scanning electron microscopy (SEM), and X-ray diffraction (XRD). Additionally, the tensile properties and thermal stability of the composite film were examined. X-ray diffraction (XRD) analysis indicated the presence of the diffraction peak of the DTG 101 crystal plane. SEM observation of TPU-4%DTG showed that the photocatalytic nanoparticles were evenly dispersed on the fiber membrane without visible agglomeration. TPU-4%DTG presented a maximum fracture stress of 17.2128 N and an elongation at a break of 335.43%. The photocatalytic performance study revealed that TPU-4%DTG was capable of eliminating over 99% of methylene blue (MB) within 10 h, and even after five cycles of photocatalytic experiments, the removal rate of MB remained above 90%.
