研究了氧化锌纳米棒在用二次阳极氧化法制备的二氧化钛纳米管模板表面的电沉积生长。与一次阳极氧化法对比,以二次阳极氧化法获得的氧化钛纳米管薄膜为模板,更有利于形貌均一、取向一致的ZnO纳米棒的电沉积生长,并且在电解质溶液中添加六次甲基四胺(HMT)、适当延长沉积时间均可提高ZnO纳米棒的结晶度和择优生长趋势。当沉积电压为1.0~1.5 V时,可获得形貌规则的ZnO纳米棒;而电压继续增大时,ZnO沿c轴择优生长趋势消失,电沉积产物氧化锌纳米棒由六边形氧化锌纳米片取代。
The electrodeposition of zinc oxide nanorods on the surface of titanium dioxide nanotubes prepared by secondary anodic oxidation was studied. Compared with the anodic oxidation method, the titania nanotube film obtained by the secondary anodic oxidation method is more conducive to the electrodeposition growth of ZnO nanorods with uniform morphology and uniform orientation, and the addition of six times in the electrolyte solution Tetramethyltetraamine (HMT), proper extension of the deposition time can improve the crystallinity and preferred growth trend of ZnO nanorods. When the deposition voltage is 1.0 ~ 1.5 V, the morphology of ZnO nanorods can be obtained; and the voltage continues to increase, the preferred growth of ZnO along the c-axis growth trend disappears, the electrodeposition of zinc oxide nanorods hexagonal zinc oxide nano Substitution
