Layered perovskite-like oxide Bi 3 Ti 1.5 W 0.5 O 9 has been synthesized by the method of high-temperature solid-state reaction. The X-ray diffraction study showed that compound is single-phase and structure family Aurivillius phases (AP) with parameters close to orthorhombic unit cell corresponding space group A2 1 am. temperature dependences relative permittivity ε/ε 0 loss tangent tgsigma ar...

Oxide materials with a perovskite-derived layered structure often show better photocatalytic performance compared to nonlayered of similar composition. Here we investigate the catalytic activity for oxygen evolution reaction (OER) on surfaces Carpy–Galy oxides Sr2Ta2O7 and Sr2Nb2O7. We find that (010) surface parallel layering shear plane is not relevant photocatalysis. The (100) perpendicular ...
