Abstract
Breaking through the stoichiometry barrier: As the diameter of silver particles is decreased below a critical size of 32 nm, the molar ratio of aqueous Hg II to Ag 0 drastically increases beyond the conventional Hg/Ag ratio of 0.5:1, leading to hyperstoichiometry with a maximum ratio of 1.125:1 (see figure). Therein, around 99 % of the initial silver is retained to rapidly form a solid amalgam with reduced mercury. Copyright © 2012 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
