Among numerous photocatalytic materials, the metal oxide of perovskite-type offers themselves as one of the remarkable photocatalytic materials.
The perovskite materials possess diverse and interesting properties, such as the oxygen content in the materials, that lead to high catalytic activity and can be easily doped with metals in the preferred amount [2, 3].
Of these materials, Strontium titanate (STO) is well recognized as a promising photocatalytic material [1, 3].
