Six-membered-ring inorganic materials for electrochemical applications

Six-membered-ring (SMR) inorganic materials have many common features. They can be exfoliated to 2D nanostructures, or grown into 2D nanostructures with appropriate base materials, then assembled to unique microstructures/macrostructures; most of them can achieve both fast electron mobility and high density of state with unique topological state; and their microstructures and electronic structures can be controlled to realize a variety of functions. Aiming to better understand the functions and develop the potential applications for electrochemical reactions, we summarize three main application scenarios of SMR inorganic materials: charge storage, reaction confinement, and reaction acceleration. The functions and mechanisms of SMR inorganic materials to modifying the electrochemical reactions are well discussed. Finally, further developments of SMR inorganic materials for electrochemical reactions are reviewed.
