Synthesis of ZnO Nanorods Arrays on ITO and Their Photoelectrochemical Performance

摘要

Tapered ZnO nanorod arrays are synthesized on indium-tin oxide (ITO) using a two-step hydrother-mal method. The influence of the growth temperature on the structure, morphology and photo-electrochemical (PEC) performance is investigated. The synthesized nanorods having an average diameter of about 100 nm are found to be nearly perpendicular to the substrate and exhibit good PEC properties. Our results suggest that the growth temperature is a crucial parameter to determine the physical and chemical properties of the nanorod arrays.
