“…Wang and et al synthesized an actiniae-like carbon nanotube assembly (3D-CNTA) as a catalyst for electrocatalytic water splitting, which is also derived from ZIF-67. The water electrolyzer also exhibits stable performance under the operating cell voltage 1.68 V for 10 h. Besides the above two examples, there are also reported works on ZIF-67-derived CoP x /carbon composites, [61,109,110] CoSe x / carbon composites, [51,62,[111][112][113] CoS x /carbon composites, [114] cobalt-doped carbon nanotubes, [115][116][117] and other Co-doped carbon matrices. carbon core-shell particles on the tips of the nanotubes (see Figure 10).…”

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...

“…[10] For this purpose, rational catalyst design lies in constructing novel electrocatalysts with favourable structures. [33,35,41,64,83,101] Structure engineering is a promising and indispensable strategy to develop improved catalysts in this respect, [102] and plays www.advancedsciencenews.com a critical role in integrating all components to make full use of their functionalities. Until now, a variety of nanostructures or architectures based on MOF-derived materials, such as edge-rich strucutures, [48] core-shell structures, [64,83] sandwich structures, [33] porous nanowire array structures, [35] and threedimensional hierarchical structures, [101] have been synthesized and widely investigated.…”

great potential to meet our ever-growing demand for energy. These devices appear most promising due to their high energyconversion and storage efficiencies, portability, which can mitigate the intermittent distribution of the aforementioned energy in space and time, and environmental benignancy. [6][7][8][9][10] Fundamentally, these electrochemical systems or devices involve different energy-conversion reactions, such as the oxygen reduction reaction (ORR), oxygen evolution reaction (OER), hydrogen evolution reaction (HER) and electrochemical CO 2 reduction (ECR), which provide energy by directly converting chemical energy (e.g., methanol, ethanol, zinc, and hydrogen) into electrical energy, or store energy vice versa. [6][7][8][9][10][11][12] The intrinsically sluggish kinetics of these reactions highlights the critical role of electrocatalysts. In this regard, the development of advanced electrocatalysts has always been the technological bottleneck that hinders the practical applications of these energy techniques at any appreciable scale. [7][8][9][10][11][12] Currently, noble-metal-based materials (e.g., Pt, IrO 2 , RuO 2 , and Au) are considered to be state-of-the-art catalysts for a variety of energy devices, [13][14][15][16] such as proton exchange membrane fuel cells (PEMFCs). [13] In spite of their outstanding catalytic performance for many electrochemical reactions, the high cost and scarcity of these noble metals severely hamper their large-scale commercialization. [17] Further, precious metal catalysts face issues with poisoning when exposed to a range of chemical compounds like methaol and carbon monoxide, leading to significant activity loss. [18] Therefore, extensive studies have focused on the development of alternative electrocatalysts with high activity, long stability, low cost, widespread availability, and facile synthesis. [8][9][10]19,20] To replace precious-metal-based catalysts, a wide range of non-noble-metal materials, especially transition-metal-based materials and metal-free carbon materials, have been intensively investigated as electrocatalysts for different applications. [21] Most of these electrocatalyst candidates show great promise in energy-conversion reactions. Nevertheless, very few alternative materials have yet to achieve superior electrochemical properties to those of noble-metal-based catalysts. Fortunately, the accumulation of experimental and theoretical studies have significantly advanced our knowledge on the chemical and physical nature of various candidate materials. [10][11][12] For example, our group has shed light on the activity origin of The key challenge to developing renewable and clean energy technologies lies in the rational design and synthesis of efficient and earth-abundant catalysts for a wide variety of electrochemical reactions. This review presents materials design strategies for constructing improved electrocatalysts based on MOF precursors/templates, with special emphasis on component manipulation, morphology control, and structure engineering.
