A silver nanocomposite on a matrix of the natural polysaccharide guar gum cross-linked with borate bridges was obtained. Metallic nanoparticles were synthesised by the reduction of silver ions under the action of the polysaccharide. The formation of the nanocomposites was confirmed by UV and IR spectroscopy and X-ray diffraction analysis. The resulting polymeric nanocomposite shows catalytic activity in the reduction of 4-nitrophenol with sodium borohydride under mild conditions.
