结果却大不同啊。。。
合成真是神奇啊。。。 | f*********j
发帖数: 1955 | 2 为什么我总是能合成出奇怪的形状呢？这回是十字架形的，上回是网球拍形的，这回合
成的跟狗骨头似的。。。
下面那个也是有大有小。。真无语。。。：（
难道是我做的前躯体不work么。。。唉

1.what was your objective? (难道是我做的前躯体不work么?)
2. you have to make sure the synthesis conditions were exactly the same for
your 2 particles? ( temperature, time, crystalline, so on so on?)
3. I even thought your figure 1 was an enlarged (zoomed in) part of figure 2
. u sure the sacle bar was right? ( hehe I should not dout this though)
4. it would be worth further sutdying on why you got different particles (为

发帖数: 7091 | 5 particle size was bigger in Fig.1 (50-100 nm) than Fig 2 ( <10 nm). did you
use higher concentrations of the reactants (precusors???) for Fig 1, or less

发帖数: 1955 | 6 哈哈。。。控温、原料用量，整个反应过程都一样。。。
唯一不同的是，两个反应通气有差别，我的反应需要氩气保护，但是我觉得不规则形状
的样品反
应过程中我其实通气没有搞好，氧气以及水分没有排干净。。。恩
