Crystal OH mediating pathway for hydrogen peroxide production via two-electron water oxidation in non-carbonate electrolytes.

ABSTRACT: Water oxidation presents a promising avenue for hydrogen peroxide (H₂O₂) production. However, the reliance on alkaline bicarbonate electrolytes as an intermediate has limitations, such as H₂O₂ decomposition and a narrow pH effectiveness range (7-9), restricting its utility across wider pH ranges. This study unveils a crystal OH mediating pathway that stabilizes SO₄OH* as a crucial intermediate. Basic copper carbonate (Cu₂(OH)₂CO₃) tablets, commonly found on cultural relics, exhibit the capability to generate H₂O₂ in neutral or acidic non-bicarbonate electrolytes. By leveraging this crystal OH mediating strategy, considerable H₂O₂ production in Na₂SO
