Study of high-efficiency and free secondary pollution TiO2 based photocatalyst has become the one of the most urgent problems in improving the decolorization effect of the waste water from printing and dyeing mill. In this work, a novel self-standing Ag2O@YSZ-TiO2 p-n nanoheterojunction nanofibrous membrane was designed for ultraviolet (UV) photocatalyst by a facile combination of electrospinning technique and precipitation process. Moreover, the UV photocatalytic performance of the flexible AZT p-n nanoheterojuction nanofibrous membranes with a band gap energy of 2.89 eV and good reversibility of 5 cycles, was superior to the commercial catalyst P25 for photocatalytic degradation of methylene blue. Furthermore, the photocatalytic mechanism of the flexible Ag2O@ YSZ-TiO2 nanofibrous photocatalyst was proposed by the electron transition in Ag2O/TiO2 p-n nanoheterojunction, which showed a new insight to development of flexible and high-efficiency nanoheterojunction nanocrystalline photocatalytic membranes.
