Metal dication cross-linked polymer network colloids as an approach to form and stabilize unusually small metal nanoparticles
DOI: 10.1039/C3CC41778F, CommunicationZichuan Ye, Behzad Tangeysh, Bradford B. Wayland
Reduction of Cu(II) dications immobilized by cross-linking into colloidal polyacrylate networks is used to illustrate a general strategy to produce relatively small ([similar]3 nm) metal Cu particles which can be further tuned to smaller size ([similar]1.5 nm) by partially substituting Ca+2 for Cu+2 as a non-reducible M+2 cross-linker in the colloidal network.
