Abstract: The acetone-sensing properties of the undoped and Pd doped perovskite-type oxides NdFeO3
were investigated from room temperature
to 400°C.

摘要：
我们研究了未参杂和钯参杂的钙钛矿型氧化物 NdFeO3 从室温升温到400℃下的的丙酮气敏特性。
The perovskite-type NdFeO3 was synthesized by a sol-gel method, and the dopants Pd with the content from 1wt% to 5wt% were implanted into NdFeO3 nanoparticles by
翻译：使用溶胶 - 凝胶法合成了钙钛矿型NdFeO3，并通过热扩散向NdFeO3纳米微粒中植入了添加量在1wt% 到5wt%的掺杂剂钯到。
X-ray diffraction (XRD) and scanning electron microscopy (SEM) techniques show that NdFeO3 is an orthorhombic structure with the average particle size of about 40 nm.
翻译：通过X-射线衍射（XRD） 和扫描电子显微镜（SEM ）技术的检测结果表明NdFeO3是斜方晶结构的，平均粒径约40nm 。
A giant acetone-sensing response of 675.7 is observed when the Pd content in NdFeO3 powders is about 3wt%.
翻译：当NdFeO3 粉末里的钯添加量在3wt%的时候，观测到了一个巨大的丙酮气敏响应值在675.7。
The response and recovery time of the sensor to the 5×10–4 acetone gas are 16 and 1 s, respectively.
翻译：传感器对浓度为5×10–4的丙酮气体的响应和恢复时间分别是16s和1s。
At the same time, it performs a good selectivity to acetone gas and may be a new promising material candidate for the acetone-sensor development.
翻译：同时，它表现出对丙酮气体的良好的选择性，并且有望作为一个新的材料用于丙酮气体检测元件的开发。
