Antimonic acid and N-doped antimonic acid, solid acids with d10electron configuration, are reported as novel photocatalysts for rhodamine B (RhB) degradation under visible light irradiation. They show much higher activities in comparison with P25 and photolysis. However, the extent of degradation abilities for RhB was not consistent with the formation rate of the active OH radicals under visible light irradiation. [ABSTRACT FROM AUTHOR]
