Functional role of single-atom catalysts in electrocatalytic hydrogen evolution: Current developments and future challenges

Electrocatalysis Mechanism and Structure–Activity Relationship of Atomically Dispersed Metal‐Nitrogen‐Carbon Catalysts for Electrocatalytic Reactions

“…Furthermore, excessive carbon emissions have also broken the original carbon balance in nature and destroyed the harmonious coexistence between humans and nature. [ 1 ] It is necessary to utilize surplus electric energy from renewable energy sources such as wind and solar power, to achieve the effective use of energy through oxygen reduction reaction (ORR), [ 2 ] carbon dioxide reduction reaction (CO 2 RR), [ 3 ] oxygen evolution reaction (OER), [ 4 ] hydrogen evolution reaction (HER), [ 4b,5 ] nitrogen reduction reaction (NRR), [ 6 ] and other processes to complete significantly the effective use of energy, which is an effective solution to alleviate environmental and energy issues. [ 7 ] Therefore, it is critical to speed up the development of electrocatalysts with high catalytic activity, stability, and selectivity.…”

Oxalate metal–organic framework derived atomic Ru3+-doped Co(OH)2nanosheets for a highly efficient hydrogen evolution reaction

“…Though noble metal-based materials, especially platinum (Pt) based materials, show high catalytic activity towards the hydrogen evolution reaction (HER), the high cost hinders their widespread applications. [1][2][3] Minimizing the mass loading of noble metals on cathodes by atomically dispersing the noble metals in some hosts offers the opportunity to realize costeffective noble metal-based high-performance electrocatalysts for the HER. [4][5][6] Recent studies showed that some atomic Ruloaded materials displayed considerably higher catalytic activity than the Pt-based materials.…”

A descriptor for the design of 2D MXene hydrogen evolution reaction electrocatalysts

“…The single atom catalyst is recognized as an effective means to maximize catalytic activity and signicantly reduce the presence of noble metal atoms. [1][2][3][4][5] Two dimensional (2D) materials with a large specic surface area and extreme thinness potentially provide a large number of active sites for the hydrogen evolution reaction (HER). [6][7][8][9] Therefore, the combination of a single atom catalyst and 2D material presents an alternative for the design of HER electro-catalysts.…”
