摘要
层状双金属氢氧化物(LDHs)是重要的无机非金属材料,作为一种具有离子交换性且环保的新型吸附材料,在重金属处理领域备受关注。传统方法制备出的产品颗粒大且厚,吸附能力受限。因此需要寻求一种制备工艺改善LDHs生长,进而提高吸附效率。文章总结了近年来LDHs的制备方法,对LDHs进行了简单概述,重点介绍了LDHs的形貌调控机理,为今后的研究提供一些参考依据。
Layered double hydroxides(LDHs)are important inorganic materials and have attracted much attention in the field of heavy metal treatment as a new adsorbent material with ion exchange properties and environmental protection.The products prepared by conventional methods have large and thick particles with low adsorption capacity.Therefore,there is a need to find a preparation method to guide the directional growth of LDHs and thus improve the adsorption efficiency.In this article,we summarized the preparation methods of LDHs in recent years,give a brief overview of LDHs,and focus on the morphology regulation mechanism of LDHs to provide some reference basis in future research.
