摘要
以离子液体-水为混合溶剂,通过水热法制备了Mg/Al水滑石,借助XRD、SEM、TG、N2吸附-脱附、红外等技术对产物的晶相、晶体相貌特征、热稳定性及比表面积进行了表征。结果表明,在离子液体-水混合溶剂中可生成具有良好晶型和热稳定性的水滑石,并且与纯水相比,离子液体-水混合溶剂中制备的水滑石具有较高的结晶度,并且具有较大的比表面积和较窄的孔径分布。
Mg-Al LDHs was synthesized by hydrothermal method using ionic liquid-water mixture as solvent ; various studies such as X-ray photoelectron spectrometry, SEM, TG, nitrogen adsorption-desorption isotherms and Fourier transform-IR spectroscopy were conducted. The results show that the Mg-Al LDHs,were better in crystallinity and thermal stability compared with that prepared in pure water. Moreover, they possessed bigger BET surface area and narrower pore size distribution.
