dc.description.abstract | Various morphologies of Co-containing precursors such as nanorods, nanosheets, and nanocubes were prepared by controlling the solvothermal reaction using cobalt acetate. L(+)-lysine, and oxalic acid, all of which were successfully converted into Co3O4 nanostructures without morphological variation. The gas responses of these Co3O4 nanosheets, nanorods, and nanocubes to 100 ppm C2H5OH at 300 degrees C were 10.5, 4.7, and 4.5 times higher than those of the Co3O4 agglomerated nanopowders, respectively. In addition, the selectivity to C2H5OH over CO and H-2, as well as the response/recovery kinetics, were significantly improved. These enhanced gas-sensing characteristics were attributed to the less agglomerated nanostructures of the sensing materials. (c) 2010 Elsevier B.V. All rights reserved. | - |
