Layered Inorganic Cationic Frameworks beyond Layered Double Hydroxides (LDHs): Structures and Applications

Abstract

Layered double hydroxides (LDHs), a typical layered inorganic cationic material, have been widely studied as ion‐exchanger, catalyst and polymer additives. The past few decades have seen rapidly increasing interest in non‐LDH type 2‐dimensional inorganic cationic frameworks. Their novel properties derived from structural and compositional diversity cast a light on the field where LDHs show limited performance. This minireview will discuss the structure, synthesis and applications including anion‐exchange and catalysis of non‐LDH type 2‐dimensional inorganic cationic frameworks and present the prospective for researchers working on.
