Abstract

Hydrothermally grown iodate, K₈Ce₂I₁₈O₅₃, featuring polar 0D [Ce(IO₃)₈]⁴⁻ units, has shown the highest visible light driven (VLD) photocatalytic activity in metal iodates reported before. The enhanced VLD photocatalytic property results from a synergistic effect between the narrow band gap and polar 0D [Ce(IO₃)₈]⁴⁻ units, as confirmed using first principles calculations.
