society is still heavily relying on chemical fuels. Therefore, the essential and realistic approaches to environmental and energy issues remain to be the exploration of clean and sustainable energy sources, in order to meet the ever-increasing energy demand. Thanks to its high energy density and environmental friendliness, hydrogen fuel comes into play as a muchanticipated new energy carrier, which is under intensive studies in the academic field. [4] Furthermore, we are already in the new era witnessing the transformation of hydrogen-powered technologies from science fictions to realities. UK is already in the process of replacing their traditional diesel-powered double decker buses with the hydrogen-powered version, which aims to phase out the former by 2018. [5] China announced its world's first hydrogen-powered tram, which was put into business service in the latter half of 2017. [6] Mercedes-Benz had even started its development of personal hydrogen-powered car, and Toyota had commercialized its hydrogen fuel-cell car branded "Mirai." [7,8] However, one critical issue remains to be the conflict between the hydrogen production efficiency and the demand for the mass distribution of hydrogen-powered technologies.Current industrial hydrogen production methods include coal gasification (followed by water-gas shift reaction), steam reforming, cryogenic distillation, and water splitting. [9] Coal gasification and steam reforming utilize the reaction between conventional fossil fuels and water to produce syngas (primarily CO and H 2 ) or CO 2 and H 2 mixture. However, both reactions require high temperatures (can be over 1000 °C) and pressures, which is an energy intensive process and has strict requirements on infrastructures. [10] The reaction products also need to be further separated to obtain relatively high-concentration of hydrogen. Cryogenic distillation takes the advantage of difference in gas boiling points, which can be applied to separate hydrogen from other gas components in the former two hydrogen production methods. However, cryogenic distillation is also an energy intensive process for low-temperature gas liquification. In comparison, hydrogen evolution reaction (HER) through water splitting is much-favored because of the following three prominent advantages: 1) Water splitting can be carried out at room temperature and ambient pressure, which is less restricted by infrastructure requirements. 2) Oxygen and hydrogen can be produced separately or selectively, which eliminate the need for gas separation. 3) Both the hydrogen source Highly efficient hydrogen evolution reactions (HERs) will determine the mass distributions of hydrogen-powered clean technologies in the future. Metal-organic frameworks (MOFs) are emerging as a class of crystalline porous materials. Along with their derivatives, MOFs have recently been under intense study for their applications in various hydrogen production techniques. MOF-based materials possess unique advantages, such as high specific surface area, crystalline porous str...

batteries, sodium-selenium (Na-Se) batteries, Li-tellurium (Li-Te) batteries, and Na-S batteries) have their own distinctive applications due to their various characteristics. To explore new materials with high performance, large studies have been devoted to the development of nextgeneration batteries.Porous carbon (PC) materials possess many unique properties due to their large surface areas, high conductivity, large pore volumes, high thermal stability, and surface functionalities, [22][23][24] leading to their wide use in energy storage and conversion. Traditionally, PC can be obtained via various methods, such as the direct heat treatment of organic precursors, hard template or nanocast methods, and soft template methods. However, the production of PC from these methods cannot be scaled-up because of certain barriers (disordered structure with wide size distributions, complicated processes, etc.). [23,25,26] Metal-organic frameworks (MOFs) have drawn wide research interest as a novel class of porous materials that are crystalline materials consisting of metal ions and organic ligands. [4,21,[27][28][29][30][31] Since the report on the MOF-templated synthesis of PC in 2008, [32] a large number of studies have been reported on the use of MOFs as suitable precursors/templates for carbon synthesis. [22,26,[33][34][35] At present, a large number of studies indicate that zeolitic imidazolate framework-8 (ZIF-8), MOF-5, MIL-125 (Ti) (MIL = Materials of Institute Lavoisier), and ZIF-67 with excellent thermal stability and unique porous structures are the more commonly used MOF precursors (Scheme 1). [3,36,37] All of them, ZIF-8, possessing nitrogen-containing ligands, has high porosity and thermal stability. [38][39][40] MOF-5 possesses excellent thermal stability, high porosity, and so on. [41] MIL-125, an active photocatalyst, includes cyclic octamers of TiO 2 octahedra. [42,43] ZIF-67 has a tunable pore aperture, highly stable structure, and catalytic activity. [37,44,45] The above-mentioned MOFs have been widely used for gas adsorption, molecular separation, catalysis, batteries, supercapacitors, and so on. [13,14,33] Moreover, carbon hybrids containing nanostructured metal species (e.g., metal oxides (MOs)) are likely to form under in situ carbonization conditions. [46] Compared with the carbonaceous materials from conventional precursors, MOF-derived carbon materials have significant advantages with high specific surface areas, tailorable porosities, unique morphologies, and easy functionalization with other heteroatoms. [14,23,31] For example, Xu and co-workers [47] obtained 1D carbon nanorods via the pyrolysis The applications of carbon and carbon-based materials with high porosity, high surface area, and functionalities based on metal-organic framework precursors and/or templates have attracted significant research interest in recent years, particularly in the field of batteries. The chemical and physical properties of carbon and carbon-based materials obtained by the heat treatment of various metal-organic ...

“…The authors associated the enhanced HER performance to the induced carbon-surface defect density, which favored the diffusion of Se atoms through Co atoms, and made the best use of the exposed active surface area. Lin et al [178] synthesized MOF-derived cobalt diselenide (MOF-CoSe 2 ) built with CoSe 2 nanoparticles anchored into nitrogen-doped graphitic carbon through in situ selenization of Co-based MOFs. The N-doped MOFs derived architecture benefited of the high conductivity provided by the abundant active reaction sites, ensuring a robust contact between CoSe 2 nanoparticles and N-doped carbon support.…”

This review summarizes recent progress in the development of cobalt-based catalytic centers as the most potentially useful alternatives to noble metal-based electrocatalysts (Pt-, Ir-, and Ru-based) towards the oxygen reduction reaction (ORR), oxygen evolution reaction (OER), and hydrogen evolution reaction (HER) in acid and alkaline media. A series of cobalt-based high-performance electrocatalysts have been designed and synthesized including cobalt oxides/chalcogenides, Co–Nx/C, Co-layered double hydroxides (LDH), and Co–metal-organic frameworks (MOFs). The strategies of controllable synthesis, the structural properties, ligand effect, defects, oxygen vacancies, and support materials are thoroughly discussed as a function of the electrocatalytic performance of cobalt-based electrocatalysts. Finally, prospects for the design of novel, efficient cobalt-based materials, for large-scale application and opportunities, are encouraged.
