AbstractBaCO3 nanoparticles with different morphologies including needle-like, rod-like, bird's nest-like and flower-like have been successfully synthesized by the microwave homogeneous precipitation method using BaCl2·2H2O, NaOH and (NH2)2CO as raw materials with the help of different guide reagents, such as citric acid (CA), sodium triphosphate (STPP) and ethylene diamine tetraacetic acid (EDTA). Their phases and morphologies were characterized by X-ray powder diffraction (XRD) and scanning electron microscopy (SEM), respectively. The characterization results show that different guide reagents have little effect on the phase structure and composition of products while they play significant roles in determining the morphology of products. All the synthesized BaCO3 nanoparticles have typical orthorhombic structures that are well-crystallized.

Zinc Salts

In this article, ZnO nanopowders formed from different zinc salts such as acetate, nitrate and sulphate were prepared via homogeneous precipitation followed by refluxing route. Several analytic techniques such as XRD, TEM, and UV-Vis were used to make characterizations of the as-synthesized samples. The results showed that ZnO nanopowders prepared from the sulphate and nitrate salts have merely close crystalline size values, and a smaller crystalline size was obtained for the ZnO formed from acetate counter ions. The band gap of the samples synthesized with the counter ions (CH3COO-, NO3-, and SO42-) were 3.05 ± 0.02, 3.14 ± 0.02 and 3.16 ± 0.02, respectively.
