In spite of much progress in gas-phase catalysis, applying such catalysts in the field of renewable energy coupled with electrochemistry remains a challenge due to their limited durability in electrolyte. Here, we report a robust and atomically dispersed hybrid catalyst formed in situ on a hematite semiconductor support during photoelectrochemical oxygen evolution by electrostatic adsorption of soluble monomeric [Ir(OH)<sub>6<\/sub>]<sup>2-<\/sup> coupled to positively charged NiO<sub>x<\/sub> sites. The alkali-stable [Ir(OH)<sub>6<\/sub>]<sup>2-<\/sup> features synergistically enhanced activity toward water oxidation through NiO<sub>x<\/sub> that acts as a \u00ab\u00a0movable bridge\u00a0\u00bb of charge transfer from the hematite surface to the single iridium center. This hybrid catalyst sustains high performance and stability in alkaline electrolyte for &gt;80 h of operation. Our findings provide a promising path for soluble catalysts that are weakly and reversibly bound to semiconductor-supported hole-accumulation inorganic materials under catalytic reaction conditions as hybrid active sites for photoelectrocatalysis.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>DOI: 10.1038\/s41467-017-01545-w Authors: Chunhua Cui, Marc Heggen, Wolf-Dietrich Zabka, Wei Cui, J\u00fcrg Osterwalder, Benjamin Probst, Roger Alberto Abstract: Atomically dispersed supported catalysts can maximize atom efficiency and minimize cost.
