Size-selective olefin hydrogenation by a Pd nanocluster provided in an apo-ferritin cage.

Abstract

Deep penetration by substrates through the size-restricted channels of an apo-ferritin cage results in size-selective olefin hydrogenation at the Pd nanocluster core (see picture). The encapsulated zero-valent cluster is synthesized in situ by chemical reduction of PdII ions in the apo-ferritin cage.
