Efficient photocatalytic H2O2 production by ionized AIE conjugated polyelectrolytes

Abstract

Two water-dispersible, ionized AIE conjugated polyelectrolytes were designed to significantly enhance hydrogen peroxide (H₂O₂) production, achieving 37- and 53-fold higher productivity, respectively, compared to their non-ionized forms. Notably, TPEQN⁺ achieved an impressive yield of 2.19 mmol g⁻¹ h⁻¹ without use of sacrificial agents.
