Abstract
Abstract Artificial photosynthesis using carbon nitride (g-C 3 N 4 ) holds a great promise for sustainable and cost-effective H 2 O 2 production, but the high carrier recombination rate impedes its efficiency. To tackle this challenge, we propose an innovative method involving multispecies iodine mediators (I − /I 3 − ) intercalation through a pre-photo-oxidation process using potassium iodide (suspected deteriorated “KI”) within the g-C 3 N 4 framework. Moreover, we introduce an external electric field by incorporating cationic methyl viologen ions to establish an auxiliary electron transfer channel. Such a unique design drastically improves the separation of photo-generated carriers, achieving an impressive…
