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.
