The interlayer regulation of layered materials for electrocatalysis

Electrocatalysis driven by clean electricity has attracted significant interest for its environmentally friendly potential. To this end, high-performance electrocatalysts are required to accelerate reaction rates. Layered materials have attracted considerable research interest for various electrocatalytic reactions and due to their rich crystal structures and flexible electronic structures. Their structural anisotropy and interlayer space between the host layers provide a unique confined microenvironment for accommodating diverse guest species. This review concentrates on the interlayer regulation of layered materials, summarizing the common layered materials and corresponding intercalated species used in electrocatalysis. The influence of interlayer species on the crystal structure, electronic structure, and electrocatalytic performance of layered materials is discussed. In addition, a perspective on future opportunities in the field of interlayer regulation of layered materials in electrocatalysis is highlighted.
