Abstract

Photophysical and photocatalytic properties of Ba ₅Nb ₄O ₁₅ with four-layered perovskite structure were investigated. The band gap of Ba ₅Nb ₄O ₁₅ was 3.9 eV. A broad emission band of green photoluminescence was observed at 77 K. NiO/Ba ₅Nb ₄O ₁₅ pretreated by H ₂ reduction followed by O ₂ oxidation showed a high activity for water splitting under UV light irradiation.
