EcoEnergy, EarlyView.Schematic illustration comparing the charge transfer dynamics and catalytic reaction over the (left) pristine carbon nitride and (right) Bi‐doped carbon nitride photocatalysts. In the pristine system, random charge diffusion and rapid recombination limit catalytic efficiency. In contrast, the Bi‐doped system establishes a robust internal electric field
