Beschreibung
Zusammenfassung:	The invention belongs to the technical field of photocatalytic materials, and particularly relates to a PANBiOBrW18O49 heterojunction nanofiber photocatalyst as well as a preparation method and application thereof. The preparation method comprises the following steps: dissolving polyacrylonitrile in N, N-dimethylformamide, stirring and dissolving, and carrying out electrostatic spinning to obtain PAN nanofibers; the preparation method comprises the following steps: adding bismuth nitrate and sodium bromide into a solvent, stirring to carry out a hydrothermal reaction, adding PAN nanofibers, cooling, washing with water, and drying to obtain a PANBiOBr nanofiber photocatalyst; the preparation method comprises the following steps: dissolving a tungsten salt in absolute ethyl alcohol, stirring until the solution is blue, adding PANBiOBr nanofibers, carrying out a hydrothermal reaction, cooling, washing with water, and drying to obtain the PANBiOBrW18O49 heterojunction nanofiber photocatalyst.
