A Pt-intercalated K{sub 4}Nb{sub 6}O{sub 17} was prepared by ion exchange between (Pt(NH{sub 3}){sub 4}){sup 2+} and K{sup +} ions followed by H{sub 2} reduction. After aqua regia treatment for the removal of the platinum on the external surface of K{sub 4}Nb{sub 6}O{sub 17}, it showed an activity for photocatalytic overall water splitting without a reverse reaction.
