N2 - Three compounds, SrTa2O6, Sr4Ta 2O9, and Sr5Ta4O15, were synthesized by a polymerizable complex method. Their photocatalytic activities for water splitting into H2 and O2 were tested and compared against previously published results for Sr2Ta 2O7. It was found that the efficiency of the catalysts decreases in the following order: Sr2Ta2O7 >Sr5Ta4O15 > SrTa2O 6 > Sr4Ta2O9. The relationship between photocatalytic activities and crystal structures is discussed.
