Synthesis of bismuth oxide nanoparticles by the polyacrylamide gel route

A polyacrylamide gel route has been adopted for the preparation of bismuth oxide nanoparticles. Thermal behaviour of the polyacrylamide gel has been studied by means of thermogravimetry (TGA). The formation of monoclinic Bi2O3 nanocrystallites is confirmed by X-ray diffraction (XRD). Transmission electron microscopy (TEM) investigation revealed the average particle size of Bi2O3 nanoparticles to range from 30 nm to 50 nm.
