Ultrafast reaction mechanisms in multimolecular Ir–Co catalytic assemblies for hydrogen evolution
Nanosecond optical and X-ray spectroscopy with theoretical calculations reveal the formation of a photo-induced distorted tetrahedral Co<sup>I</sup> intermediate in two Ir/Co multimolecular assemblies and indicate its protonation as the rate limiting step for H<sub>2</sub> photocatalysis. Substitution of the catalysts' pyridine group on the para position by -COOEt improves the protonation efficiency.
