Decouple H₂O₂ Electrosynthesis From Microenvironmental Decomposition via Atomic Site Density Engineering. [PDF]

Angew Chem Int Ed Engl
Using defect‐rich Co‐N2O2 single‐atom catalysts as a model system, this work reveals that atomic site density governs the competition between H2O2 electrosynthesis and microenvironmental decomposition during 2e−‐ORR. Optimised site isolation suppresses HPRR and HDR, thereby establishing a site‐density principle to balance H2O2 formation and ...

Accelerating water dissociation to achieve ampere-level hydrogen peroxide electrosynthesis in brine and seawater

Nature Communications
Ampere-level hydrogen peroxide (H2O2) electrosynthesis in brine and seawater via two-electron oxygen reduction reaction (2e− ORR) is promising, but limited by the slow water dissociation and insufficient protons in neutral media.
