纳米铜氧化物的制备及气敏特性研究

Study on the preparation and gas sensitivity properties of nano-copper oxide

分别采用CuCl2,Cu(NO3)2和CuSO4溶液制备出CuO和Cu2O,并测定了其对丁烷、乙醇、汽油、氢气的气敏特性.结果表明:采用CuCl2溶液制备的CuO或Cu2O的灵敏度较高,选择性较好,且Cu2O比CuO的气敏性好.

CuO and Cu_2O were prepared in solutions of CuCl_2,Cu(NO_3)_2 and CuSO_4,respectively.The gas sensing properties were determined against butane,ethanol,gasoline and hydrogen,respectively.The results indicate that CuO and Cu_2O prepared in the solution of CuCl_2 has higher sensitivity,better selectivity,and the gas sensing property of Cu_2O was better than that CuO.
