Synthesis, Structural Characterization, and Catalytic Activity of Flower Like ZnO Nanostructures

Abstract

Tageteserecta flower like zinc oxide nanostructures composed of hexagonal nanorods were synthesized via sonochemical method at room temperature. The synthesized nanomaterials exhibited wurtzite hexagonal phase structure with the single crystalline nature. The diameter of the individual nanorods that constitute the flower shaped zinc oxide structures is in the range of 120-160 nm. The sonication time effectively determined the morphological properties of the prepared materials. The catalytic activity of prepared zinc oxide nanostructures towards N-formylation reactions were evaluated without any surface modification and the nanostructures exhibited good reaction yield with the prompt recyclability behavior.

Effect of barium doping on structural and optical properties of zinc oxide nanoparticles synthesized by microwave hydrothermal method

“…In the second step, the ZnO nuclei arise continually with the repeatedly generated Zn(OH) 2 particles. As there is no temperature difference between zinc nitrate and NaOH solutions, the nucleation rate becomes high . In this case, an anisotropic columnar growth may proceed by repeated nucleation and epitaxial growth at the top and side faces of the particles resulting in the formation of flower‐like particles .…”

Optimization of CVD parameters for long ZnO NWs grown on ITO/glass substrate

“…ZnO as nanostructures have been found useful in many applications such as optoelectronics [3], photovoltaic [4], gas sensors [5], dye-sensitized solar cells [6,7], catalytic activity [8] and photo catalytic activity [9]. Several methods have been reported for the synthesis of various ZnO nanostructures, such as hydrothermal [10], sonochemical [11,12], sol-gel [13][14][15] and microwave irradiation [16].…”
