“…Strain can effectively modulate the electronic states of surface atoms, which in turn affects the speed of electrocatalytic reactions. 42,43 Lattice strain structures 44 and defect-induced structures are the main types of strain-engineering applications for metallic materials. Core-shell structural materials and solid-solution alloys 45 are typically grouped together, as shown in Fig.…”

“…The OER is the step with the highest energy consumption during water electrolysis. The overpotential required for water electrolysis is primarily used to overcome the reaction energy barrier of the OER [16–19] . According to the volcano diagram obtained from theoretical calculations, the oxides of precious metals, such as Ru and Ir, have the best standard free energy and are ideal catalysts for the OER.…”

With abundant metal site and tunable electronic structure, MXene is considered as a promising electrocatalyst for the conversion of energy molecules. In this review, the latest research progress on inexpensive MXene-based catalysts for water electrolysis is summarized. Typical preparation and modification methods and their advantages and disadvantages are briefly discussed, with a focus on the regulation and design of the surface interface electronic states, which improve the electrocatalytic performance of MXene-based materials. The main strategies for the electronic state modification include end-group modification, heteroatom doping, and heterostructure construction. Some limitations of MXene-based materials, which should be considered in the rational design of advanced MXene-based electrocatalyst, are also discussed. Finally, prospects for the rational design of Mxene-based electrocatalysts is proposed.

“…Sustainable energy sources can reduce the reliance on fossil fuels (coal, petroleum, and natural gas) and minimize carbon emissions. The most promising clean energy carrier today is hydrogen (H 2 ), with a high weight energy density of 122 kJ g –1 and zero carbon emissions. − Despite this, the application of H 2 is usually restricted by its cost, storage, and transportation constraints. Therefore, it is crucial to develop green, efficient, and convenient H 2 production technologies to make universal use of H 2 possible.…”

Hydrogen gas (H 2 ) as a fuel has the advantages of high energy density (122 kJ g −1 ) and zero carbon emissions. To meet the growing demand for H 2 in the future, green, efficient, and convenient production technologies must be developed. The Al−H 2 O reaction, which produces H 2 by reacting aluminum (Al) with water (H 2 O), is considered a rapid method for producing H 2 . However, Al−H 2 O creates a protective oxide layer on the surface of Al, preventing the production of H 2 . In this study, we developed a simple method for forming Al− GaInSn alloy by brushing GaInSn−Al 2 O 3 grease onto an Al plate to form an Al/GaInSn−Al 2 O 3 /Al sandwich structure. Al 2 O 3 in the sample supports GaInSn, prevents the leakage of GaInSn, and promotes its penetration into the Al lattice to form Al−GaInSn alloy. By forming a liquid phase within the alloy, GaInSn increases the accessibility of Al to the reaction. As a result, the Al−GaInSn alloy can rapidly react with pure H 2 O to produce H 2 at room temperature conditions, with yields as high as ∼93.2%. It was interesting to find that dye-polluted water (methyl orange) could be synchronically purified by the Al−H 2 O reaction at the same time.
