摘要：

The preparation of microcrystalline cellulose samples containing intercalated silver(0) particles includes two main stages: diffusion of silver ions from aqueous AgNO3 into the microcrystalline cellulose matrix, followed by reduction of the silver ions bound to cellulose macromolecules to Ag(0) and growth of Ag(0) particles inside the cellulose matrix and on its surface. Mechanisms of interaction of silver ions with cellulose as reducer and with other reducers and ligands are considered.
