Silver nanoparticles have been prepared using reductive polysaccharides as protecting agents and silver nitrate as precursor via a facile green approach. The possible formation mechanism of silver nanoparticles was proposed. The composites synthesized at high concentration of polysaccharide were calcined in different atmosphere. Macroporous sponge of silver and silver nanoparticle/amorphous carbon composite have been obtained in air and nitrogen, respectively. The as-synthesized samples were characterized by XRD, SEM, TEM, UV-vis and BET adsorption methods.

Key words: silver nanoparticle, polysaccharide, green chemistry, silver/carbon composite
