Photocatalytic Water Splitting over Spontaneously Hydrated Layered Tantalate A2SrTa2O7·<i>n</i>H2O (A=H, K, Rb)

Abstract

Abstract A series of layered perovskite-type tantalates with hydrated interlayer space, A2SrTa2O7·nH2O (A=H, K, Rb), exhibited efficient photocatalytic activity for water splitting into H2/O2 mixture under UV irradiation without loading metal co-catalysts.
