“…For cyanide-based MOFs, Prussian blue analogues have also been directly used and provide the added benefit that it is easy to prepare mixed metal MOFs from them. 348 A few groups have also explored the potential for Co-based imidazolates (particularly ZIF-67) for the OER, with little sign of broader structural degradation under alkaline OER conditions. 347,349 ZIF-67 itself is not a particularly good OER catalyst; 349 however, by growing ZIF-67 on Co(OH) 2 , the catalyst activity improved to 280 mV at −10 mA cm −2 .…”

More than 95% (in volume) of all today's chemical products are manufactured through catalytic processes, making research into more efficient catalytic materials a thrilling and very dynamic research field. In this regard, Metal Organic Frameworks (MOFs) offer great opportunities for the rational design of new catalytic solids, as highlighted by the unprecedented number of publications appearing over the last decade. In this review, the recent advances in the application of MOFs in heterogeneous catalysis are discussed. MOFs with intrinsic thermo-catalytic activity, as hosts for the incorporation of metal nanoparticles, as precursors for the manufacture of composite catalysts and those active in photo and electrocatalytic processes are critically reviewed. The review is wrapped up with our personal view on future research directions.

“…A small number of MOF-based materials have emerged as electrocatalysts for water splitting, mainly due to their low electrical conductivity and stability. [12,227,228] 2D MOFs have been demonstrated to have enhanced conductivity and more exposure to active sites. For instance, Duan et al developed a 2D bimetallic MOF on conductive substrates for high-efficiency water electrolysis via a dissolution-crystallization process.…”

carrier with an extremely high energy density (approximately 142 MJ kg −1 ) and zero-carbon content, has been regarded as a promising clean fuel. [1,2] In this context, electrochemical water splitting, which converts electricity into storable hydrogen, is a viable and efficient solution to mitigate severe energy shortages and greenhouse gas emissions. [3] Among these strategies, hydrogen and oxygen evolution reactions, which occur on the cathode and anode, respectively, in a water electrolyzer, are considered as two critical half-reactions of the water-splitting process. [4] Theoretically, water splitting requires a thermodynamic Gibbs free energy (ΔG) of approximately 237.2 kJ mol −1 , corresponding to a standard potential (ΔE) of 1.23 V versus a reversible hydrogen electrode (RHE), which allows the thermodynamically uphill reaction to occur in the electrolyzer. [5] However, the unfavorable thermodynamics and resulting large overpotential are the main barriers to the scalable implementation of water electrolysis for hydrogen generation. [6,7] Currently, noble metal-based electrocatalysts exhibit the most efficient activity for water splitting, particularly Pt-based hydrogen evolution reaction (HER) catalysts and Ir/Ru-based oxygen evolution reaction (OER) catalysts. [8,9] Nevertheless, the scarcity and high price of precious metals severely impede their widespread use in commercial water-splitting applications. Taking these limitations into Electrochemical water splitting has attracted significant attention as a key pathway for the development of renewable energy systems. Fabricating efficient electrocatalysts for these processes is intensely desired to reduce their overpotentials and facilitate practical applications. Recently, metal-organic framework (MOF) nanoarchitectures featuring ultrahigh surface areas, tunable nanostructures, and excellent porosities have emerged as promising materials for the development of highly active catalysts for electrochemical water splitting. Herein, the most pivotal advances in recent research on engineering MOF nanoarchitectures for efficient electrochemical water splitting are presented. First, the design of catalytic centers for MOF-based/derived electrocatalysts is summarized and compared from the aspects of chemical composition optimization and structural functionalization at the atomic and molecular levels. Subsequently, the fast-growing breakthroughs in catalytic activities, identification of highly active sites, and fundamental mechanisms are thoroughly discussed. Finally, a comprehensive commentary on the current primary challenges and future perspectives in water splitting and its commercialization for hydrogen production is provided. Hereby, new insights into the synthetic principles and electrocatalysis for designing MOF nanoarchitectures for the practical utilization of water splitting are offered, thus further promoting their future prosperity for a wide range of applications.
