Bimetallic Colloids: Silver and Mercury

摘要: Mercury ions, Hg2+, are radiolytically reduced in an aqueous silver sol. The plasmon absorption band of is blue-shifted, which explained by the formation a solid mercury layer around particles. metal deposition stops when particles carry about two monolayers and additionally forms colloidal Hg Chemisorbed SH- I- ions damp silver−mercury particles, effect being less pronounced with increasing content It concluded that collective excitation electron gas still strongly contributes to optical absorption, even they shell. chemisorption equilibrium shifted desorption side upon excess electrons on
