类水滑石(LDHs)和蒙脱土(MMT)都属于二维层状黏土,通过将LDHs与MMT复合可得到不同结构的LDHs/MMT复合材料,如板对板交替结构、花状结构及板层混合交替结构,已应用于吸附、催化、荧光、油水分离领域。介绍了LDHs/MMT复合材料的制备方法,对其在各领域的研究进展进行了综述,最后对其发展前景进行了展望。
Both layered double hydroxides (LDHs) and montmorillonite (MMT) belong to two-dimensional layered clays.By combining layered double hydroxides and montmorillonite,the LDHs/MMT composites with different structures can be obtained,such as alternating plate-to-plate structure,flower-like structure and mixed alternating layer structure,which have been used in the fields of adsorption,catalysis,fluorescence,and oil-water separation,etc.In this paper,the preparation methods of LDHs/MMT composite were introduced,and the research progress of LDHs/MMT composites was reviewed.Finally,the development of LDHs/MMT was prospected.
