Metal dication cross-linked polymer network colloids as an approach to form and stabilize unusually small metal nanoparticles

摘要

Reduction of Cu(Ⅱ) cations immobilized as cross-linkers in polyacrylate network colloids produce relatively small (～3 nm) Cu metal particles which are further tuned to smaller size (～1.5 nm) by partially substituting Ca~(+2) for Cu~(+2) in the polymer network colloid.
