Silver clusters intercalation into the cellulose matrix I. Mechanisms of diffusion-reduction interaction of microcrystalline cellulose and silver ions

Preparation of microcrystalline cellulose-Ag _n systems consists of two main stages: preliminary diffusion of Ag ⁺ ions from aqueous AgNO ₃ solutions into the cellulose matrix and subsequent reduction of Ag ⁺ ions bound to the molecules of microcrystalline cellulose, with the formation of Ag _n clusters intercalated into MCC. Different mechanisms in the interaction of silver ion with reducers and ligands are assumed. It was shown that they depend on the reducer and ligand type and lead to the preparation of different cellulose-silver intercalates containing metallic silver clusters.
