abstract = {Atomically dispersed supported catalysts can maximize atom
efficiency and minimize cost. 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)6]2−
coupled to positively charged NiOx sites. The alkali-stable
[Ir(OH)6]2− features synergistically enhanced activity
toward water oxidation through NiOx that acts as a
“movable bridge” of charge transfer from the hematite
surface to the single iridium center. This hybrid catalyst
sustains high performance and stability in alkaline
electrolyte for >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.},
