Abstract

A new visible light responsive photocatalyst Sn(II)-doped SrNb₂O₆ has been developed for water reduction and water oxidation reactions. First-principles calculations revealed that the Sn(II) dopant created a new occupied state in the band gap which resulted in photocatalytic activities under visible light irradiation.
