摘要

Water splitting driven by renewable energy is considered to be a promisingapproach for sustainable H2 production. However, the simultaneous generationof H_2 and O_2 requires the use of a membrane to prevent the gas mixing,which significantly limits the flexibility of H_2/O_2 separation and H_2 transportation,impeding the direct use of renewable sources. In recent years, theconcept of decoupled water electrolysis has been proposed along with theutilization of solid-state redox mediators, by which the H_2 and O_2 generatedat different times and spaces could be separated in absence of membrane.Here, a comprehensive overview of the decoupled water electrolysis usingsolid-state redox mediators (SRMs) is presented. After a brief introduction,the SRMs are systematically summarized, including the structural features,the reaction mechanisms, and the properties of decoupled systems. In addition,the coupling of decoupled hydrogen production with other valuablereactions is also involved. Finally, this work discusses the challenges andperspectives for the decoupled water splitting system for commercializationand sustainable H_2 production.
