Abstract
The Fe<sup>III</sup>/Fe<sup>II</sup>redox couple in the amorphous FeO<sub>x</sub>cocatalyst on the Bi<sub>4</sub>TaO<sub>8</sub>Cl photocatalyst captures photoexcited electrons and facilitates the multielectron (6-electrons) reduction of IO<sub>3</sub><sup>−</sup>, thus boosting O<sub>2</sub>evolution under visible light.
