Realizing the regulated carrier separation and exciton generation of Bi24O31Cl10via a carbon doping strategy

A novel carbon doping strategy induced by an organic salt is successfully developed. Improved carrier separation and exciton binding energies (E_b) are achieved on C-doped Bi₂₄O₃₁Cl₁₀, which provides excellent photocatalytic CO₂ reduction and persistent ¹O₂ generation.
