Ultrafast Reaction Mechanisms in Multimolecular Ir-Co Catalytic Assemblies for Hydrogen Evolution
Abstract
Nanosecond optical and X-ray spectroscopy with theoretical calculations reveal formation of a photo-induced distorted tetrahedral CoI intermediate in two Ir/Co multimolecular assemblies and show its protonation as the rate limiting step for H2 photocatalysis. Substitution of the catalysts´ pyridine group on the para position by -COOEt improves the protonation efficiency.
