Abstract

Increasing energy demands and its impact on the environment make it necessary to look for alternative renewable energy sources. Hydrogen is considered as energy vector but on earth, free hydrogen is not available and found in the compound state. In this study, Ba_xSr_1-xTiO₃ (x = 0.00, 0.05, 0.10 and 0.20) photocatalysts are prepared by sol-gel method for water splitting. XRD patterns showed the formation of the pure cubic structure of SrTiO₃. It was observed that the optical absorption of SrTiO₃ was increased by increasing Ba content. Solar to hydrogen conversion efficiency of SrTiO₃ photocatalyst were increased by increasing Ba doping.
