英文摘要：

Obtaining fuels（e.g. hydrogen） from solar water splitting is one of the important pathways to develop clean energy. The water oxidation of half-reaction of water splitting is an important and speed-limited step in overall water splitting. To develop efficient, stable, and easy-made water oxidation catalysts（WOCs） is the key to achieve sufficient water splitting. Layered double hydroxides（LDHs） have received extensive attention in catalytic water oxidation because of its adjustable chemical compositions and unique two-dimensional layered structure. Besides acting as electrochemical water oxidation catalysts, LDHs also exhibit advantages in photo-（photoelectro-）chemical water oxidation. The progress in the LDHs and their composites as WOCs is summarized. It is expected that this review could provide inspiring ideas and helpful guidelines in the structural design of high-efficiency water oxidation catalysts.
