Abstract: Layered double hydroxides (LDHs) refer to a class of clays with diverse brucite-like layers and intercalated anions, which have attracted increasing interest in the field of catalysis. Benefiting from the atomic-scale distribution of metal cations in the brucite-like layers and the ordered arrangement of diversified interlayer anions, the LDHs display great potential as the precursors to prepare catalysts in that the catalytic sites could be highly dispersed. The approaches to prepare catalysts from LDHs as precursors include, but not limited to, exfoliation of the brucite-like layers, confinement by the brucite-like layers, intercalation, and/or nanosheet arrays. The latest development of the catalyst preparation using LDHs as precursors was mainly summarized.

Key words: layered structure, intercalated structure, precursor, high dispersion
