Abstract
Complex three-dimensional nanosheet structure of ZnxFeyO was prepared by highly stable co-sputtering oblique angle deposition. Scanning electron microscopy was employed to observe surface morphology evolution of ZnxFeyO with different Fe concentrations. X-ray diffraction was employed to analyze compositions of ZnO, ZnFe2O4, and ZnFe2O4/Fe2O3 with Fe doping. Furthermore, specific nanostructures of ZnxFeyO decreased band gap and increased visible-light absorption ability. The ZnFe2O4/Fe2O3 sample exhibited higher photocatalytic efficiency than those of other films for the degradation of methylene blue. Addition of Fe led to the enhancement of photoelectrochemical properties of ZnFe2O4/Fe2O3 compared to pure ZnO and Fe2O3, and photocurrent response of ZnFe2O4/Fe2O3 was ~10 times than that of pure ZnO at constant potential of −0.2 V (vs. Ag/AgCl).
