Abstract

Following the recent discovery of a Sillén-Aurivillius perovskite Bi₄NbO₈Cl with a stable photocatalytic activity for water oxidation under visible light, we studied a structurally related intergrowth compound Bi₆NbWO₁₄Cl. It also works as a stable O₂-evolving photocatalyst in a Z-scheme water splitting system, but has a slightly wider band gap than that in Bi₄NbO₈Cl. These results suggest the importance of the Sillén-Aurivillius framework, offering possible band gap tuning by varying structural motifs and their sequence in the Sillén-Aurivillius-related systems.
