• • Achieved a H2O2 production rate of 12099 μmol g−1 h−1 from water and O2 without sacrificial agents, representing a 25% year-on-year increase in China's supply capacity and a viable route to meet the projected $1.85 billion global market by 2029.
• • Demonstrated an apparent quantum efficiency (AQE) of 19% at 500 nm, indicating that over one-fifth of incident photons at that wavelength are converted to chemical energy, a critical benchmark for solar-driven industrial synthesis.
• • Extended light absorption to 700 nm (near-infrared), enabling utilization of a broader solar spectrum and achieving a solar-to-chemical energy (SCC) efficiency of 1.38%, which is competitive with natural photosynthesis and prior metal-free photocatalysts.
• • Nitrogen substitution creates built-in electric fields via electronegativity and dipole moment changes, enhancing charge separation and interfacial electron transfer, directly addressing the bottleneck of sluggish charge kinetics in metal-free photocatalysts.
