Synthesis of Silver Nanoparticles by Using Bamboo Hemicellulose as Template in Aqueous Solution

摘要

Hemicellulose was separated from bamboo using alkaline method. Silver nanomaterials had been prepared using the hemicellulose as template and silver nitrate as precursor via a green approach. The synthesized samples were characterized by UV-vis, XRD, and SEM techniques. UV-visible spectrum and XRD diffraction pattern revealed that the silver ion (Ag~+) had been reduced to the metallic silver nanoparticles (Ag~0). The results demonstrated that after calcination at 500°C in air atmosphere, nano Ag/C compound was obtained. The hemicellulose acted as an effective nanoreactor for the in situ synthesis of silver nanoparticles. This novel procedure provides a facile and environmental way to manufacture silver nanoparticles for various applications.
