摘要

Layered double hydroxide (LDH), a kind of 2D layered materials, has been recognized as the promising anti-corrosion materials for metal and its alloy. The microstructure, physical/chemical properties, usage in corrosion inhibition and inhibition performance of LDH have been studied separately in open literature. However, there is a lack of a complete review to summarize the status of LDH technology and the potential R&D opportunities in the field of corrosion inhibition. In addition, the challenges for LDH in corrosion inhibition of metal-based system have not been summarized systematically. Herein, we review recent advances in the rational design of LDH for corrosion inhibition of metal-based system (i.e. Mg alloy, Al alloy, steel and concrete) and high-throughput anticorrosion materials development. By evaluating the physical/chemical properties, usage in metal-based sys-tem and the corrosion inhibition mechanism of LDH, we highlight several important factors of LDH for anti-corrosion performance and common features of LDH in applying different metal alloys. Finally, we provide our perspective and recommendation in this field, including high-throughput techiniques for combinatorial compo-sitional design and rapid synthesis of anticorrosion alloys, with the goal of accelerating the development and application of LDH in corrosion inhibition of metal-based system.
