Figure 6

(a) Schematic of the energy bands of (BiO)2CO3 and Bi2O3 and the transfer of photo-generated charges in BOC-based heterojunctions under simulated solar light (λ > 290 nm) irradiation. (b) DMPO-ESR spin-trapping spectra of (BiO)2CO3, BOC-400, BOC-450 and Bi2O3 for the detection of hydroxyl radicals (⋅OH) in aqueous solution under UV light irradiation.
