Surface Area Study of the Nanocrystalline Zinc Oxide Synthesized by Reverse–Micellar Method

Abstract :

Zinc Oxide (ZnO) nanoparticles were synthesized by water-in-oil microemulsions with CTAB as the surfactant, 1-butanol as the cosurfactant, isooctane as the non-polar phase. These nanoparticles were decomposed at 450 �C in air to obtain nanoparticles of zinc oxide. Transmission electron micrographic (TEM) analyses revealed the particle size of the nanoparticles to be in the range 18-38nm. The average grain size is 25 nm. The specific surface area of ZnO nanoparticles as calculated using BET method was found to be 62.922 m2g-1
