Structural characterization and surface environment of ZnO nanoflowers

In this paper,zno nanoflower was successfully obtained by precipitation method using zinc nitrate and sodium hydroxide at ph 11.5. the aggregate sturucture evolutions were characterized by xrd,sem,and fesem while the elemental composition of the materials was determined by edx. the petals of the nanoflower are of varying sizes. the crystalline size of the nanoparticles is in the range 39.5-53.1 nm and the calculated surface area has been found to be 27.1 g/m2. infrared study reveals that the nano crystals are not homogeneous and the chemical structural environment has shown hydroxide layer attached on the surface of the zno nanoparticles. this work has provided some knowledge on the structural and surface properties of zno nanomaterials.
