Research Progress of Hydrotalcite-like compounds

Hydrotalcite-like compounds has layered structure and unique properties. Rich surface hydroxyl groups and interlayer anions make it have excellent heavy metal adsorption capacity. The variable valence manganese element in the laminate gives it good catalytic performance. This paper introduces the concept, structure, preparation methods and application of hydrotalcite-like compounds in detail, in order to provide reference for academic research and industrial application of environment function material.
