Abstract：One-dimensional metal oxide nanostructured materials , such as nanotubes , nanorods and nanowires have aroused tremendous research interest due to their distinctive geometrical morphologies , novel physical and chemical properties , and potential applications in nanoscale optical and electric de-vices.In this paper we present a one-simple hydrothermal synthesis of 1D ZnO nanorods with well-de-fined morphology and small diameter (<30 nm),and the morphology, crystal phase, photoresponse and specific surface area of the as-prepared samples are characterized by a series of techniques .We demon-strate that ZnO nanorods exhibit a significantly photocatalytic activity toward degradation of HCHO , for liquid-phase degradation of HCHO , the degradation efficiency over HCHO is 90.9%and stable activity;for gas-phase degradation of HCHO ,the conversion of HCHO is maintained at 95.6%over ZnO nano-rods, which corresponds to an average mineralization ratio of 94.5%.No obvious deactivation is observed over a ZnO nanorod .
