Novel Hydrothermal Synthesis of Flower Like ZnO Nanostructures and Investigation of their Gas – Sensing Properties | Chapter 7 | Recent Progress in Science and Technology Vol. 5

 Flower like nanostructures of ZnO have existed successfully contrived by a novel hydrothermal technique. Various sample characterization systems, including XRD, FESEM, SEM, TEM, have existed employed. The synthesised ZnO samples exhibited a explicit crystal makeup of hexagonal phase. The average crystallite proportion for ZnO sensors was estimated expected 31 nm. The flower shaped nanorods were ∼84 nm in diameter and ∼ 1 µm in time. The response to the lowering gas NH3 was evaluated in agreements of the operating temperature, nervousness, response time/ improvement time of the ZnO-located gas sensor. At a working hotness of 230∘C, the lowest discovery limit for ammonia gas was establish to be 5 pm.
