Rapid and Template Free Synthesis of ZnO Nanorods and Analysis of their LPG Sensing Properties
نویسندگان
چکیده
ZnO nanorods (diameters∼25 nmand lengths∼145-150 nm) were synthesized by using a simple solochemical method and their LPG sensing properties were investigated. The ZnO nanorods exhibited outstanding gas sensingcharacteristics such as, higher gas response (∼502 to 50ppm LPG at 300 ◦C), extremely rapid response(∼6-7 s), fast recovery (∼6–7 s), excellent reproducibility, good sensing selectivity and relatively lower operating temperature(∼300◦C). The experimental results clearly demonstrate the potentialof using the ZnO nanorods as sensing material in the fabrication of LPG sensors.

Template-free CuO nanorods were synthesized through a three-step chemical method with no water-insoluble materials. The first step included the preparation of a Cu-complex, which was obtained from dipicolinic acid, L-lysine, and copper nitrate. Then, as the second step, the obtained solution was allowed to be relaxed for a week to and formation of some blue single-crystals single crystals, whic...

Ethanol (C2H6O) sensitivity of zinc oxide (ZnO) thin film has been studied in present work. Semiconductor thin films of zinc oxide (ZnO) were deposited onto alkali-free glass substrates by the sol–gel method and dip-coating technique. The ZnO sol was synthesized by dissolving zinc acetate dehydrate in ethanol, and then adding Tetra ethanol-amine. The as-coated films were preheated at 150 ºC fo...

ZnO nanorods array films were coated on a glass template through a two-step chemical process. First, a sol-gel spin coating method was used to produce a ZnO seed layer and after that, the ZnO nanorods arrays were grown on it through a low temperature aqueous method. Synthesized films were studied by scanning electron microscope (SEM) and X-ray diffractometer (XRD). X-ray diffraction results sho...
