“…[35] However, for most metal elements, the bonding energy with intermediates of such coordination structure is not optimal, showing unsatisfactory ORR activity. [36] The number of coordinated nitrogen atoms could be adjusted by changing the pyrolysis temperature [37] of the precursor or changing the nitrogen source. [38] Thus, the catalytic activity of non-iron-based catalysts could be improved.…”

On the one hand, Fenton‐like reactions are common side reactions in electrocatalytic oxygen reduction reaction (ORR). The generated reactive oxygen species (ROS) could damage the active sites of single‐atom catalysts (SACs), thereby affecting the stability of the catalysts. On the other hand, the Fenton‐like reaction could generate radicals with strong oxidative properties, which could be used in the degradation of pollutants and tumor therapy. In this review, we summarize strategies to limit the occurrence of Fenton‐like reactions and improve the stability of SACs. In addition, the promotion of Fenton‐like reactivity of SACs and its application in related fields are also concluded.

“…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.
