Synthesis and ethanol sensing properties of CuO nanorods coated with In2O3
Source abstract
Abstract
Abstract CuO/In 2 O 3 core–shell nanorods were fabricated using thermal evaporation and radio frequency magnetron sputtering. X-ray diffraction and transmission electron microscopy showed that both the cores and shells were crystalline. The multiple networked CuO/In 2 O 3 core–shell nanorod sensors showed responses of 382–804%, response times of 36–54 s and recovery times of 144–154 s at ethanol (C 2 H 5 OH) concentrations ranging from 50 to 250 ppm at 300 °C. These responses were 2.3–2.8 times higher than those of the pristine CuO nanorod sensor over the same C 2 H 5 OH concentration range. The origin of the enhanced ethanol sensing properties of the core–shell nanorod sensor is discussed.
