Abstract
Er3+ doped ZnO-TiO2 nanofibers with diameter of 100～200 nm were prepared by electrospinning mothed after calcined at high temperature, using polyvinylpyrrolidone(PVP), Zn(NO3)2·6H2O, Er(NO3)3·5H2O, Ti(OC4H9)4 asraw materials. The composite nanofibers were characterized by XRD, SEM, and UV-V respectively. Effects of different calcined temperatures on structure and photocatalytic degradation were investigated. The results indicated that the crystallinity becomes better with the increasing of calcination temperature. The composite nanofibers had the best effects of photocatalytic degradation of methylene blue, when Er3+ doping content was 0.3 wt.% and calcined temperature was 500 °C.
