[求助] 氧化锌纳米棒制备已有2人参与

问一个问题,文献中说使用基板晶种生长法制备氧化锌纳米棒的时候,在基板浸入生长液90℃生长的时候要求基板悬浮在生长液中,这怎么水平悬浮啊
用什么方法能使基板悬浮呢

取15 mL超纯水同等体积的浓盐酸(36-38 wt.%)混合,在搅拌条件下,逐滴加入0.5 mL钛酸四丁醋,继续搜拌,至获得一澄清透明溶液备用。另外,将FTO导电玻璃分别在丙酮、异丙醇和乙醇中超声清洗10 min,最后用超纯水清洗。将 ...

例如Synthesis of ZnO NW films. A typical procedure for synthesizing the ZnO NW films is carried out as in the literature [29].
Firstly, a seed layer was deposited on the conductive F-doped SnO2
(FTO) glass by sol–gel method using the zinc acetate dihydrate
(Zn(Ac)2·2H2O, 0.5 mol L−1) as the precursor and then the substrates coated with ZnO seed layer were calcined at 500 ◦C for
1 h. The precursor aqueous solution for the growth of ZnO NW
was prepared in advance by mixing the hexamethylenetetramine
(HMT, 0.025 mol L−1) and Zn(Ac)2·2H2O (0.025 mol L−1) in deionized water, and stirring for 20 min at 0 ◦C. Then the FTO substrates
with ZnO seed layer were immersed into this solution immediately and sealed in a flask in an oven at 95 ◦C for 7 h. Then the
films were rinsed in deionized water thoroughly and subsequently
heated at 500 ◦C for 1 h. The film obtained in this step was marked
as ZNW。Journal of Photochemistry and Photobiology A: Chemistry 219 (2011) 132–138。第一步就是晶种

动动脑筋,不要以为是什么高深的科学,只是一个小小的技巧问题而已,让一个东西悬浮在水中有好多方法,密度大你就吊着他不要让他下沉,密度小你就拉着他不要让他漂浮

【答案】应助回帖

把导电玻璃割的长一些,有晶种的那一面朝下放
