Abstract

Iron hexacyanoruthenate, a Prussian blue analogue, was employed as a precursor to load highly dispersed Fe and Ru dual cocatalysts on an oxyiodide Ba₂Bi₃Nb₂O₁₁I, resulting in significantly enhanced activity for non-sacrificial O₂ evolution with a Fe³⁺ electron acceptor under visible light irradiation.
