The data on preparation, structure and morphology of microcrystalline cellulose and cellulose-based composites, those have oxide component as filler are reported. It is shown that depending on raw materials origin and processing degree cellulose samples reveal various degree of crystallinity (in the range 64–77 %). Obtained composites reveal even lesser crystallinity degree ≈ 57%. Detailed analysis of surface morphology was performed with using of scanning electronic microscopy. It was found the studied samples contains plates with sizes ~ 20–50 μ those consist of close-packed grains of 5–10 μ size. In the case of composites some oxide nanoparticles (sizes up to 200 nm) were incorporated into grains of microcrystalline cellulose. It was shown that action of light on “cellulose”+"AgNO3” composite led to reduction of silver. This observation indicates a possibility for using of such composites as bactericide materials.
