Effective electronic tuning of Pt single atomsviaheterogeneous atomic coordination of (Co,Ni)(OH)2for efficient hydrogen evolution

“…S6). 32,65,66 The "fluctuation behavior" of the LSV was due to relatively large streams of bubbles being generated at the very large current density, which regularly interrupt the mass transfer process, leading to the evident fluctuation of the polarization curve. Furthermore, an appropriate and widely used frequency range of low (0.01 Hz) to high (100 K Hz) frequency was applied for the HER impedance measurements in this study 67,68 .…”

Electrocatalytic sulfion recycling assisted energy-saving hydrogen production using CuCo-based nanosheet arrays

“…[1][2][3][4][5] Compared with hydrogen produced by fossil fuel cracking, the electrolytic hydrogen production process using renewable energy sources such as solar or wind energy can achieve zero carbon emissions and is gaining widespread attention. [6][7][8][9][10] However, due to the thermodynamic drawback of the anodic oxygen evolution reaction (OER), the cell voltage of electrolytic water usually exceeds 1.8 V, and most of the electrical energy is converted into oxygen with low commercial value through the anode reaction. [11][12][13] For this reason, some recent studies have attempted to replace the OER with thermodynamically favorable anodic small molecule oxidation reactions, [14][15][16][17] such as ethylene glycol oxidation, 18 glycerol oxidation, 19,20 and 5-hydroxymethylfurfural oxidation.…”

Synergistically interactive P–Co–N bonding states in cobalt phosphide-decorated covalent organic frameworks for enhanced photocatalytic hydrogen evolution

“…Constructing interfacial chemical bonding is proven as an effective strategy to fabricate cocatalyst-integrated heterojunction photocatalysts with high catalytic performance. 28–30 This is because the chemical bonding formed between the cocatalyst and the host matrix can suppress the aggregation and leaching of the active sites during the reaction process, thus improving the recyclability. 31,32 More importantly, the resultant chemical bonding can also serve as a brigade to accelerate the transfer of charge carriers relative to conventional interactions, thus enhancing the activity.…”
