摘要：
In this work, ZnO nanofibers (ZNFs) were successfully prepared via a simple electrospinning technique using polyvinylpyrrolidone (PVP) and zinc acetate dihydrate (Zn(CH(3)COO)(2)center dot 2H(2)O) as precursors. The obtained ZNFs have an average diameter of ca. 95 nm and are composed of crystalline wurtzite phase. Methylene blue (MB) dye was used to investigate the photocatalytic performance of pure ZNFs. The study confirms that ZNFs have favorable catalytic activity, and the best degradation efficiency of MB can exceed 90% under UV light irradiation for 3 hours. In addition, we propose a possible photodegradation mechanism.
