Interfacial assembly of mussel-inspired au@ag@ polydopamine core-shell nanoparticles for recyclable nanocatalysts

Adv Mater. 2014 Feb;26(5):701-5. doi: 10.1002/adma.201303032. Epub 2013 Nov 8.

Abstract

Recyclable nanocatalysts of core-shell bimetallic nanocrystals are developed through polydopamine coating-directed one-step seeded growth, interfacial assembly, and substrate-immobilization of Au@Ag core-shell nanocrystals. This strategy provides new opportunities to design and optimize heterogeneous nanocatalysts with tailored size, morphology, chemical configuration, and supporting substrates for metal-catalyzed reactions.

Keywords: bimetallic core-shell nanocrystals; interfacial assembly; polydopamine; recyclable nanocatalysts; seeded-growth.
