Synthesis, Structure and Thermal Analysis of Silver Nanoparticles using Bakelite Composite

摘要

In present work, silver nanoparticles are synthesized using phenol and formaldehyde by chemical precipitation method. To obtain the silver nanoparticles, synthesized bakelite complex is decomposed at the 1100 °C. The formation of the synthesized bakelite composite is confirmed by the infra-red spectroscopy and nuclear magnetic resonance spectroscopy. The chemical composition and crystallographic structure of silver nanoparticles are confirmed by XRD, while scanning electron microscopy and atomic force microscopy are used to characterize the morphology of nanoparticles as well as the distribution of nanoparticle in composite. The SEM analysis indicates the ductile and catastrophic brittle fracture present on the surface of the nanoparticles. The XRD analysis revealed the size of the nanoparticle and the crystal structure which are 24 nm and orthorhombic, respectively. Thermogravimetric analysis determined the 68 % stability of compound at 900 °C and the process being endodiermic.
