[求助] Co-Al类水滑石的合成

Co-Al类水滑石的合成的合成采用硝酸钴 硝酸铝 尿素合成。请问在合成的过程中一定要通氮气保护吗?如果不同氮气保护会怎么样?

是否通氮气应该没有多少影响!

当然,我只做过Cu-Mg-Al-O, Ni-Mg-Al-O, Cu-Zn-Al-O的水滑石,没有做过Co-Al-O的!

我觉的如果你想做水滑石,应该使用氮气保护!
因为此时Co应为2+,如果不用氮气保护,Co的价态不能保护!

谢谢啦,好好看一些这些文献。我也只是刚刚想着做这个。
有时候觉得其实不通氮气就这么放置也不会这么快氧化,毕竟能养花还是需要达到一定的活化能。

Co2+不是太稳定,打算做一组通氮气的,一组不通氮气的,再看看吧。
不过,还是谢谢你啦

不通氮气主要生成碳酸根插层的水滑石

如果不加碳酸根离子不就生成不了了,就算是空气中的二氧化碳溶解的话也是很小部分的
