Abstract

Inverse opal (IO) photonic semiconductors are promising materials for photocatalysis, thanks to their slow photon properties that increase light harvesting. Here, we report, in IO TiO2-BiVO4 photonic structures, the ability not only to generate slow photons in the visible range but also to tune their frequencies and transfer their energy. Angle-resolved photocatalytic experiments revealed a 70% increase in activity in all IO structures compared to non-IO compact films and a further 20% increase when the slow photons were accurately tuned to BiVO4 electronic absorption. The synthesis and tuning strategies presented here can be extended to all solar energy conversion applications.
