Abstract

Designing hybrid organic-inorganic catalysts with bioinspired principles inspires applied catalyst development. We monitor the formation in situ and unravel the structure of a high-performance disordered hybrid cobalt oxidation catalyst. Atomistic modeling of X-ray scattering and absorption spectra identifies the catalyst as an unconventional cobalt coordination polymer of hydrated {H2O-Co2(OH)2-OH2} edge-site motifs connected by bridging hydrophobic bis-phosphine oxide ligands. The flexibility of this structural topology opens up new roads for rational design of disordered catalysts beyond molecules and solids.
