Structure Engineering of Layered Double Hydroxides (LDHs) for Heterogeneous Catalysis

Layered double hydroxide (LDH) is regarded as an advanced platform material in catalysis and attracts vast attrition recently. As a kind of two-dimensional layered material, it exhibits great advantages including cation-tunability in layer, lattice limitation, topological transformation, ion exchange and intercalation characteristics. It also can be used as building blocks for composite catalytic materials. Over 100 years, a large number of works have been accomplished and researchers made great progress on investigating the LDH-based catalytic materials. In this review, we summarize representative achievements and significant progress in recent years, which mainly include constructing high entropy catalytic material, high dispersion/stability and interfacial supported catalytic material, composite catalytic materials and nano-reactor based on LDH. Furthermore, through collecting the excellent works, we conclude the future development potential of LDH and provide a perspective.
