摘要：

ZnO nanostructure of rods and tubes was synthesized by hydrothermal method, using aqueous solutions of zinc-nitrate and hexamethylenetetramine. The experiments were conducted at 90 degrees C for 2h, 4h, 8h and 24h. The influence of reaction time on the formation of ZnO based samples with different morphologies is investigated. The structural and morphological properties were examined by X-ray diffraction (XRD) and scanning electron microscopy (SEM) analyses. The XRD results confirmed the wurtzite crystal structure of ZnO in the synthesis and formation of a secondary phase after 8h of hydrothermal treatment. The SEM investigation shows the obtaining of nanorods after 2h of reaction and formation of nanotubes at prolonged reaction time. FT-IR studies were carried out in order to ascertain the presence of various functional groups in the obtained materials. DSC analysis confirmed the modifications observed in samples obtained at different reaction times.
