Abstract

Abstract:

Salt lakes are well developed in China, which possess rich magnesium resources. The preparation of magnesium based functional materials with high-performance and high-value chemicals is an effective means to realize the sustainable development of magnesium resources in salt lake. Magnesium based layered double hydroxides (LDHs) is an important type of magnesium functional material. By virtue of the unique structural characteristics (e.g., tunability of layer metal ions and interlayer guest anions, and structure topological transformation), magnesium based LDHs have shown potential applications in petroleum, coal, fine chemistry and environmental pollution fields as precursors or supports. This article focuses on reviewing the research progress of magnesium-based hydrotalcite catalytic materials in recent years， and summarizes its structural regulation rules， so as to provide reference for the subsequent application of magnesium-based hydrotalcite catalytic materials.

Key words: magnesium resources, layered double hydroxides, structural design, catalysts
