不用種子層,氧化鋅納米棒陣列可以水熱合成嗎?文獻是這樣做的,我重復(fù)的,沒長上! 文獻如下: Preparation of ZnO NRAs on Ni Foam. In this experiment, allthe chemicals were analytical grade and were used without further purification. Ahead of the experiment, the Ni foam substrate (1 × 1cm2) was ultrasonically washed with ethanol and water for 20 min each and then placed into the autoclave liners vertically. The reaction solution was prepared by mixing 0.015 M zinc nitrate hexahydrate and 0.015 M hexamethylenetetraamine (HMTA) together with 2 mL of ammonia in 70 mL of distilled water under constant magnetic stirring for 30 min. The reaction solution was then transferred into the autoclave liners and kept sealed at 90 °C for 24 h. After the reaction,the Ni foam coated with a white product was washed with deionized water, and thus the ZnO NRAs were obtained. 請教原因? |
