Merging semi-crystallization and multispecies iodine intercalation at photo-redox interfaces for dual high-value synthesis

Artificial photocatalytic systems based on graphitic carbon nitride are improving, but production of high-value products at electron and hole sites is challenging. Here, the authors report a system using graphite-phase carbon nitride modified with potassium iodide/triiodide eutectic salt to generate H2O2 and benzaldehyde.
