By union of graphitic carbon nitride polymer with reduced graphene oxide (rGO, ≤1 wt%) via π–π stacking interaction, the band structure could be well modulated. As a result, significant increase photocurrent was observed (e.g., when biased at 0.4 V vs.Ag/AgCl, anodic became 300% higher after doping). Not merely interesting in itself, also used as general dopant for semiconductors band-structure engineering.
