abstract = "Layered perovskite-like niobate CsBa2Nb3O10 has been synthesized in a pure single-phase state forthe first time using both nitrates and carbonates of cesium and barium.

A potential reason for its chemical inactivitymay consist in partial disordering of cesium and barium cations between the interlayer space and perovskiteslab, hindering the interlayer ion exchange. Optical bandgap energy of CsBa2Nb3O10, being equal to 2.8 eV,potentially allows using visible light (λ < 443 nm) for driving photocatalytic reactions.
