“…In addition, two more peaks were observed at 331 and 379 cm −1 and are attributed to the E 2H -E 2L (multi-phonon process) and A 1T modes, respectively. 31,32 Multiphonon process can occur only for the single crystalline ZnO nanostructures and the obtained spectrum confirmed the single crystalline nature of the prepared nanostructures. A dominant Raman-active E 2 mode observed from the spectrum confirmed the wurtzite hexagonal phase structure 33 of the synthesized ZnO nanostructure with the high crystal quality and structural purity.…”

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.

NO2 sensing characteristics of ZnO nanorods prepared by hydrothermal method

ZnO nanorods were prepared via a hydrothermal reaction in a solution containing Zn(NO 3 ) 2 ·6H 2 O, NaOH, cyclohexylamine, ethanol and water, and their NO 2 and CO sensing behaviors were investigated. The morphology and agglomeration of ZnO nanorods could be manipulated by controlling the amount of water in the solution, which was explained by the variation in the [OH − ] due to an interaction between the water and cyclohexylamine. Sea-urchin-like and well-dispersed ZnO nanorods were prepared at low and high water content, respectively. Well-dispersed ZnO nanorods showed 1.8 fold change in resistance at 1 ppm NO 2 while there was no significant change in resistance at 50 ppm CO. The present ZnO nanorods can be used in automated car ventilation systems to detect NO 2 in the presence of CO.
