Synergy of crystallinity modulation and intercalation engineering in carbon nitride for boosted H₂O₂ photosynthesis.

ABSTRACT: Photosynthesis of hydrogen peroxide (H₂O₂) by selective oxygen reduction is a green and cost-effective alternative to the energy-intensive anthraquinone process. Although inexpensive polymeric graphitic carbon nitride (g-C₃N₄) exhibits the ability to produce H₂O₂, its disordered and amorphous structure leads to a high recombination rate of photogenerated carriers and hinders charge transfer between layers. Herein, we predict that stacked polymeric g-C₃N₄ with ion intercalation (K⁺ and I^-) can improve carrier separation and transfer by multiscale computational simulations. The electronic structures of g-C₃N₄ were tailored and modified by intercalating K^+</
