Graphical Abstract

Ab initio calculations were used for the rational design of efficient alcohol oxidation catalysts that mimic the enzyme galactose oxidase. Different ligand substitutions were explored based on natural (copper, depicted) and alternative (rhodium) metal redox centers. The calculated turnover rate for the most efficient copper-based biomimetic compound is greater than that of the natural enzyme.
