The purpose of this paper is to describe a novel method for producing zinc
oxide (ZnO). Within only 10 min of the synthesis procedure, ZnO nanoparticles
were precipitated directly from a sodium zincate after partial neutralization
with sulfuric acid. The entire synthesis process was carried out at room temperature.
There were no additives or additional operations, such as calcination,
required in the proposed method. XRD, FESEM, and BET techniques were used
to characterize the product, and XRD confirmed the formation of crystalline
ZnO devoid of other phases. Consideration of the height of XRD peaks revealed
that ZnO crystallites grow preferentially along the c-axis. FESEM revealed
particles with a diameter of 30–50 nm which was also confirmed by analysis of
the broadening of XRD peaks. Nearly spherical particles were observed by the
FESEM. These nanospheres were primarily adhered together to form platelets.
Finally, the BET analysis revealed a substantial specific surface area of 20
m2 g- 1.
