Synthesis of bismuth oxide nanoparticles using bismuth nitrate and urea

A mixture of bismuth nitrate and urea is taken in 1:5 molar ratio and heated on hot water bath. A precipitate is formed on evaporation of the water which on decomposition at 400 °C produces nanocrystalline Bi 2O 3 particles. Formation of nano crystallites of Bi 2O 3 is confirmed by X-ray diffraction...

Description
Summary:A mixture of bismuth nitrate and urea is taken in 1:5 molar ratio and heated on hot water bath. A precipitate is formed on evaporation of the water which on decomposition at 400 °C produces nanocrystalline Bi 2O 3 particles. Formation of nano crystallites of Bi 2O 3 is confirmed by X-ray diffraction (XRD) study. Transmission electron microscopy (TEM) investigations revealed for these powders an average particle size of 50 nm.
