<div>The effects of various metal dopants on the photocatalytic water splitting activity of SrTiO<sub>3</sub> -based photocatalysts were investigated using experimental studies. The SrTiO<sub>3</sub>:Rh (1%) has been found to give the best efficiency in water splitting out of the various metal-doped samples studied. However, the same host doped with other metal dopants such as Fe, V, Ga, and Sb leads to negligible hydrogen evolution even when at least Fe has a better visible light response. Our results accompanied by previously conducted theoretical studies by our group explain the high photocatalytic water splitting activity of Rh doped SrTiO<sub>3 </sub>. Furthermore, the effects of the amount of catalyst, the proportion of sacrificial agent and pH were studied for the SrTiO<sub>3</sub>:Rh (1 mol%) along with studying its activity with seawater.</div>
