The nanorods were hexagonal in shape, 50-100 nm in diameter and uniform in distribution. They exhibited homogeneous surface morphology, c-axis orientation and excellent crystalline properties. The synthesized nanorods were used to sense and detect hydrogen in a homemade gas chamber. The fabricated sensor successfully detected as low as 40 ppm hydrogen at room temperature with a very low level of power supply (16.16 μA) under a mixed background. Dynamic and repeated responses were observed with a wide range of hydrogen concentrations (40-360 ppm) at 200 °C. The developed sensor was at least 25 fold more sensitive over the literature documented Pd doped ZnO nanorods in detecting hydrogen at ambient temperature. The simplicity, low-cost, high sensitivity and high stability of the sensor materials suggested that the synthesized Pd doped ZnO nanorods could be used in hydrogen and chemical sensing devices where Pd-mediated catalysis is involved. 2014-04-23T06:22:15Z 2014-04-23T06:22:15Z 2013-08 Article Ceramics International, vol. 39(6), 2013, pages 6461-6466 0272-8842 http://www.sciencedirect.com/science/article/pii/S0272884213001090 http://dspace.unimap.edu.my:80/dspace/handle/123456789/33952 en Elsevier Ltd and Techna Group S.r.l. |
