Spontaneous adsorption of iridium chloride complex on oxychloride photocatalysts provides efficient and durable reaction site for water oxidation

The visible-light-driven O 2 evolution on oxychloride photocatalysts, such as Bi 4 NbO 8 Cl, was significantly enhanced by stirring in an aqueous solution containing IrCl 6 3– in the dark. Various characterizations indicated that highly dispersed...
