摘要
为寻求新型气敏材料,用化学共沉淀法制备了Cu2+掺杂In2O3,研究了其相结构、电导和气敏性能。结果表明:900℃热处理4h所得掺2%Cu2+的In2O3微粉制作的元件对C2H5OH有较高的灵敏度和较好的选择性,有良好的应用前景。
To explore new-type gas-sensing material,In_2O_3 doped with Cu^(2+) is prepared by chemical coprecipitation,the phase constitueats, conductance and gas-sensing properties of In_2O_3 are investigated. The results show the sensor based on the 2 % Cu^(2+) doped In_2O_3 powder sintered at 900 ℃ for 4h has a high sensitivity and selectivity to C_2H_5OH, and is promising for practical use.
