我们报道了氧化铜颗粒和片状材料的合成及其在气敏元件中的应用。通过热分解法制备CuO颗粒，而通过水热路线获得CuO片。系统研究了不同温度下CuO对NO2气体和乙醇的敏感性。结果表明，所合成的产物在200 ℃的操作温度下具有高灵敏度和快速响应/恢复时间。此外，CuO板显示出更高的灵敏度，NO2气体比相应的颗粒。这一研究表明，氧化铜片在传感器的应用潜力。(C)2007爱思唯尔有限公司保留所有权利。
We reported on the synthesis and gas-sensor application of copper oxide particles and plates. CuO particles were prepared by a thermal decomposition method, while CuO plates were obtained by a hydrothermal route. The sensitivity of the as-prepared CuO to NO2 gas and alcohol at varied temperatures was studied systematically. The results revealed that the as-synthesized products had high sensitivity and quick response/recovery time at an operating temperature of 200 degrees C. Furthermore, the CuO plates displayed higher sensitivity to NO2 gas than that of the corresponding particles. This research indicated that CuO plates have potentials in the applications of sensors.
