The Emerging Career of Strontium Titanates in Photocatalytic Applications: A Review

The growing energy demands and rapid industrialization drove the attention towards a sustainable living. The methods to a adopt renewable source of energy has made the field of heterogeneous photocatalysis so famous. The photocatalytic hydrogen production seems to be an answer for our future energy crisis. In this regard, alkaline earth metal titanates with a perovskite structure are one of the in demand materials these days. Among these, strontium titanates (SrTiO3) play an important role and have shown a potential, especially in the field of hydrogen production. This review summarizes the significance of (SrTiO3) in photocatalytic water splitting, to produce hydrogen and the photocatalytic degradation of the pollutants from the waste water. Different synthesis methods used for preparing SrTiO3 are also discussed.
