Inspired by natural enzymes, hierarchical catalytic supramolecular nanostructures were developed by the co‐assembly of hemin and glucose oxidase (or Au NPs) with the photosensitive ferrocene–tyrosine (Fc‐Y) molecule. Illuminated by white light, the Fc‐Y molecules are polymerized and co‐assemble with hemin into truncated polyhedrons. The Au NPs grew in situ at the surface of the co‐assembled polyhedrons, achieving ordered supramolecular nanostructures. Because the Au NPs can serve as an artificial glucose oxidase and the hemin could act as a peroxidase mimic, the supramolecular hybrid nanostructures were used to mimic natural enzymes and catalyze the glucose conversion cascade reaction. The hybrid Au NPs@Fc‐Y&hemin polyhedrons showed superior catalytic activity, good reusability, and maintained the catalytic activity over a wide temperature and pH range. The study demonstrates a feasible strategy to construct hierarchical co‐assembled supramolecular nanostructures as multi‐enzyme mimics, with potential applications in biocatalysis and biosensing.
