摘　　要：采用静电纺丝技术并经过热处理法制备了In^3+掺杂FeVO4纳米材料,利用XRD和SEM表征了材料的形貌特征和晶体结构,通过CGS-4TPs智能气敏分析系统测试了In-FeVO4材料对正丁醇气体的气敏传感性能。气敏性能测试表明,In^3+掺杂FeVO4样品在350℃下对100 ppm的正丁醇气敏响应值S达到了7.4,为纯相FeVO4的1.6倍;同时,In^3+掺杂FeVO4材料对正丁醇气体还展现出良好的选择性和稳定性。In^3+掺杂提高了FeVO4材料的电子传输能力,从而增加了材料的气敏传感性能。因此,In^3+掺杂FeVO4气敏传感材料具备优异的气敏传感性能。In-FeVO4 nanomaterials were prepared by electrostatic spinning technology and heat treatment. The morphology and crystal structure of the samples were characterized by XRD and SEM technology. The gas sensing performance of In-FeVO4 to n-butanol gas was investigated by CGS-4 TPS intelligent gas sensing system. The results show that doping with In^3+ in sample can enhance the electronic transmission ability and can increase the gas-sensitive sensing property of the material. The gas response value S of In-FeVO4 to 100 ppm n-butanol reached to 7.4 at the temperature of 350, which is 1.6 times that of pure FeVO4. Furthermore, the In-FeVO4 material shows outstanding selectivity and stability. Therefore, the In-FeVO4 material is endowed with excellent gas sensing performance.
