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...

A sustainable future demands innovative breakthroughs in science and technology today, especially in the energy sector. Earth‐abundant resources can be explored and used to develop renewable and sustainable resources of energy to meet the ever‐increasing global energy demand. Efficient solar‐powered conversion systems exploiting inexpensive and robust catalytic materials for the photo‐ and photo‐electro‐catalytic water splitting, photovoltaic cells, fuel cells, and usage of waste products (such as CO2) as chemical fuels are appealing solutions. Many electrocatalysts and nanomaterials have been extensively studied in this regard. Low overpotentials, catalytic stability, and accessibility remain major challenges. Metal nanoclusters (NCs, ≤3 nm) with dimensions between molecule and nanoparticles (NPs) are innovative materials in catalysis. They behave like a “superatom” with exciting size‐ and facet‐dependent properties and dynamic intrinsic characteristics. Being an emerging field in recent scientific endeavors, metal NCs are believed to replace the natural photosystem II for the generation of green electrons in a viable way to facilitate the challenging catalytic processes in energy‐conversion schemes. This Review aims to discuss metal NCs in terms of their unique physicochemical properties, possible synthetic approaches by wet chemistry, and various applications (mostly recent advances in the electrochemical and photo‐electrochemical water splitting cycle and the oxygen reduction reaction in fuel cells). Moreover, the significant role that MNCs play in dye‐sensitized solar cells and nanoarrays as a light‐harvesting antenna, the electrochemical reduction of CO2 into fuels, and concluding remarks about the present and future perspectives of MNCs in the frontiers of surface science are also critically reviewed.

Metal–organic frameworks (MOFs) are constructed by periodically alternate metal ions with organic ligands, which offer structural diversity and a wide range of interesting properties as an attractive classification of crystalline porous materials. Integration of MOFs with other size‐limited functional centers can supply new multifunctional composites, which exhibit both the properties of the components and new characteristics due to the combination of MOFs with the selected loadings. In recent years, integration of metal/metal oxide nanoparticles (MNPs) into MOFs to form the composite catalysts has attracted considerable attention due to the superior performance. In this review, the latest studies and up‐to‐date developments on the design and synthetic strategy of new MNP@MOF composite catalysts are specifically highlighted. Both the achievements and problems are evaluated and proposed, and the opportunities and challenges of MNP@MOF composite catalysts are discussed.
