Electrospinning Directly Synthesis of 0d/1d Cubi2o4@Wo3 Nanofiber Photocatalyst with S-Scheme Heterojunction

•A novel 0D/1D CuBi2O4@WO3 nanofiber photocatalyst with step-scheme (S-scheme) heterojunction was fabricated by means of the electrospinning method.•In the CuBi2O4@WO3 heterostructures, some smaller CuBi2O4 nanoparticles homogeneously distributed on the surface of WO3 nanofibers.•The CuBi2O4@WO3 composite shows excellent photocatalytic activity for TC degradation under weak visible-light irradiation.•The mechanism and driving force of charge transfer and separation in photocatalytic degradation of TC were discussed.
