The invention belongs to the technical field of nanomaterial preparation, and in particular relates to a preparation method and application of a ZnO/CNF composite material. The preparation method of the ZnO/CNF composite material comprises the following steps: (1) polyvinyl alcohol is dissolved in water to form a polyvinyl alcohol aqueous solution; (2) under stirring conditions, a soluble zinc salt is added to the polyvinyl alcohol aqueous solution, Obtain spinning solution; (3) carry out electrospinning with described spinning solution, dry, make ZnO/CNF precursor nanofiber; ( 4 ) with described ZnO/CNF precursor nanofiber, in the condition of N Under the condition of calcination, the ZnO/CNF composite material was prepared. The ZnO/CNF composite material prepared by the method of the invention has good composite performance, ZnO can be evenly loaded on the CNF, the fiber thickness is uniform and stable, and has excellent photocatalytic degradation efficiency. |
