你看看文献,第一步大部分都是做晶种,然后把带晶种的玻璃放反应釜中...

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。将配置好的溶液置入80 mL聚四氟乙稀为内衬的不绣钢反应爸中,然后将FTO导电玻璃导电的一面向下斜靠在反应签中,在150 °C保温8h。反应完成后,用水冲洗FTO导电玻璃,烘干。----这是一个博士论文里面的,晶种就是钛酸四丁酯的混合物么?

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

您好,在FTO导电玻璃上能够长出二氧化钛纳米棒,文章上也有写到普通的玻璃也可以,但是不清楚普通玻璃和石英玻璃的区别,您在玻璃基底上面做过这方面的研究么?谢谢

FTO玻璃有个导电面,催化剂得长在导电面上进行测试,普通玻璃不导电,长上也没法测试电化学

您好,我不需要测他的电化学性能,只需要测SEM规整就OK,我想问您一下,文献上面所说的Teflon-lined autoclave是什么样子的反应釜?  我用的就是一块铁疙瘩,里面有个聚四氟乙烯的内衬。
