The influence of ZnO nanoseeds on the formation of ZnO nanorods from epsilon-Zn(OH)(2) in NaOH solution at 80 degrees C was investigated, using ZnO nanoparticles with a diameter of 4-10 nm as the seeds. The experimental results indicated that the presence of ZnO nanoseeds promoted the rapid heterogeneous formation of ultrathin ZnO nanorods. Compared with the ZnO submicron rods with a diameter of 0.5-1.0 mu m, the ultrathin ZnO nanorods with a diameter of 10-15 nm were found to be more sensitive for detecting NO2 at room temperature owing to their higher variation of channel conduction to the diameter.
