摘要
A heterojunction is successfully fabricated by decorating ZnO nanorods with water-soluble, mono-dispersed ZnFe2O4 particles. In comparison with bare ZnO, the enhanced visible light absorption and photocurrent ( lambda > 420 nm) for the photoanode of the ZnO-ZnFe2O4 composite is correlated with the visible light response of the ZnFe2O4 prepared and the rapid charge transfer within the heterojunction as evidenced by the electrochemical impedance spectra.
