Generation of sub-5 nm AuNPs in the special space of the loop-cluster corona of a polymer vesicle: preparation and its unique catalytic performance in the reduction of 4-nitrophenol

Gold nanoparticles smaller than 5 nm were encapsulated in the special space of the loop-cluster corona on a polymer vesicle. They exhibited high catalytic activity in the reduction of nitrophenols, but with remarkable oxygen-induced induction times.
