An unprecedented substrate‐selective catalytic enhancement effect of an alkanethiol‐self‐assembled monolayer (SAM) on Au nanoparticles (AuNPs) is reported. In the supported 2D‐array of AuNPs, the alkanethiol‐SAM acts as a protein‐like soft reaction space in which the substrate molecules are encapsulated through non‐covalent intermolecular hydrophobic interactions, and thus catalytic reactions are accelerated at AuNP surfaces.
