Metal-organic-framework-derived metals and metal compounds as electrocatalysts for oxygen evolution reaction: A review

Abstract

Electricity-driven oxygen evolution reaction (OER) is crucial for water dissociation because it allows for sustainable and clean energy production. However, the fast reaction should be improved for industrial applications. Therefore, numerous studies have focused on designing and synthesizing high-performance catalysts with low-cost facial processes for use in the OER. Metal-organic frameworks are hybrid materials that consist of inorganic and organic components, exemplified as ideal sacrificial templates for the fabrication of efficient anode materials to be used in water oxidation. In this account, various types of MOF-derived anode materials, including metals, metal oxides, metal phosphides, nitrides, carbides, and metal chalcogenides, are discussed. In addition, we have demonstrated the advantages of MOFs and provide studies with controverted mechanisms of the OER. Finally, the current problems and prospects for the use of MOFs in the electrochemical OER are discussed. (C) 2021 Hydrogen Energy Publications LLC. Published by Elsevier Ltd. All rights reserved.
