Synthesis, conversion and comparison of the photocatalytic and electrochemical properties of ZnSe·N2H4 and ZnSe microrods

Novel ZnSe·N2H4 complex microrods with ∼2 μm in length and 100∼200 nm in diameter were successfully prepared by the solvothermal method at 110°C for 10 h, employing ZnAc2·2H2O and Se powders as the reactants, N2H4·H2O as the reductant and medium. Experiments showed that the as‐obtained complex could be further converted into pure hexagonal ZnSe in an ethanol medium at 180 °C for 10 h, and the morphology hardly changed. The as‐prepared products were characterized by X‐ray powder diffraction (XRD), Energy dispersive spectrum (EDS), IR spectrum, Thermogravimetric (TG) analysis and Field emission scanning electron microscopy (SEM). Also, their photocatalytic degradation and electrochemical property were compared. (© 2008 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
