A ‘self-activating’ Bi3TaO7–Bi4TaO8Br photocatalyst and its use in the sustainable production of pro-fluorophoric rhodamine-110

A rhodamine B photodegradation intermediate, a highly expensive rhodamine 110 profluorophore, has been extracted in a commercially sustainable way by developing a catalyst that improves its activity in every cycle, unlike other photocatalysts.
