H2O2 production via the two-electron oxygen reduction reaction (2e- ORR) offers a potential alternative to current anthraquinone method owing its efficiency and environmental friendliness. However, it is necessary determine structures of electrocatalysts with cost-effectiveness high for future industrialization demand. Herein, supramolecular catalyst composed cobalt-phthalocyanine on near-monodispersed oxidized single-walled carbon nanotube (CoPc/o-SWCNT) was synthesized solution self-assembly catalyzing 2e- ORR electrosynthesis. Benefiting from enhanced intermolecular interaction by introducing functional groups o-SWCNTs, oxidation states single-atom Co sites were tuned formation two extra Co-O bonds. Coupled structural characterizations, density-functional theory (DFT) calculations reveal that depressed d-band center site regulated axially-bridged O atoms gives rise suitable binding strength intermediates (*OOH) favor ORR. Thus, CoPc-6wt%/o-SWCNT-2 optimized synthetic parameters delivers competitive performance electrosynthesis in neutral electrolyte (pH = 7), including generation, satisfactory molar selectivity ∼83-95% long-period stability (75 h) H-cell measurement. Moreover, could also be boosted show 45 mA cm-2, recorded turnover frequency 25.3 ± 0.5 s-1 maximum rate 5.85 mol g-1 h-1 continuous accumulation 1.2 wt% flow-cell device, which outperformed most reported neutral-selective nonprecious metal catalysts.

Recent Advances in Carbon-Based Single-Atom Catalysts for Electrochemical Oxygen Reduction to Hydrogen Peroxide in Acidic Media

Nanomaterials, Journal Year: 2024, Volume and Issue: 14(10), P. 835 - 835

Published: May 9, 2024

Electrochemical oxygen reduction reaction (ORR) via the 2e− pathway in an acidic media shows great techno-economic potential for production of hydrogen peroxide. Currently, carbon-based single-atom catalysts (C-SACs) have attracted extensive attention due to their tunable electronic structures, low cost, and sufficient stability media. This review summarizes recent advances metal centers coordination environment C-SACs 2e−-ORR. Firstly, mechanism 2e−-ORR on active sites is systematically presented. Secondly, structural regulation strategies are further summarized, including center, its species configurations nitrogen or heteroatom coordination, near functional groups substitute groups, which would provide available proper ideas developing superior electrocatalysts C-SACs. Finally, we propose current challenges future opportunities regarding C-SACs, will eventually accelerate development distributed H2O2 electrosynthesis process.
