- Abstract
- Nearly complete substitution of lead into layered perovskites is a generic method of visible light sensitization for these ultraviolet (UV)-active materials. Thus, CaBi4Ti4O15 (Aurivillius phase), K0.5La0.5Ca1.5Nb3O10 (Dion-Jacobson phase), and Sr3Ti2O7 (Ruddlesden-Popper phase) are photocatalysts, all working under UV light, but their analogs containing lead (PbBi4Ti4O15, K0.5La0.25Bi0.25Ca0.75Pb0.75Nb3O10, and PbTiO3) absorb visible light and exhibit photocatalytic activity of decomposition of water under visible light.
