Abstract

Controlled localization of platinum nanoparticles (Pt NPs) at a solid support assisted by a polarized liquid–liquid interface is reported. Electrocatalytic water oxidation resulted in local pH modulation followed by the directed self-assembly of a dibenzoyl-L-cystine hydrogelator forming a structured hydrogel retaining the shape of the Pt NP deposit.
