不同热解条件下硬脂酸根插层水滑石热解时形态变化的研究

Study on morphology change of stearate radical intercalated hydrotalcite during different pyrolysis conditions

采用共沉淀法合成了镁铝物质的量比为3的硬脂酸根插层水滑石,利用FT-IR、TEM等技术分析了不同焙烧温度和焙烧时间对该水滑石焙烧产物的组分及形貌的影响,获得了至今尚未见报导的卷曲较清晰完整的纳米管状的焙烧产物。

Using co-precipitation method, stearate radical intercalated hydrotalcite that the molar ratio of Mg2＋ to A13＋ is 3 is syn- thesized. Using FT-IR and TEM, the effect of calcination temperature and calcination time on component and morphology of the calcined product is analyzed. The calcined product with clearer and complete nano-tubiform which has not been reported is obtained.
