Photophysical and photocatalytic properties of Cs 2Nb 4O 11 consisting of NbO 6 octahedra and NbO 4 tetrahedra were investigated. The band gap of Cs 2Nb 4O 11 was 3.7 eV. Broad blue photoluminescence was observed at 77 K. Pretreated NiO-loaded Cs 2Nb 4O 11 showed a high activity for water splitting under UV-light irradiation.
