Research Progress on Electrospun SnO_2 Based Nanofiber for Gas-sensing Materials

二氧化锡纳米材料具有优异的物理、化学性能,是当前研究最为广泛的气体敏感材料之一。合成二氧化锡基纳米纤维是增加材料比表面积、降低工作温度、缩短响应恢复时间的有效方法。用高效、可控的静电纺丝技术,结合掺杂、高温煅烧、水热合成等方法,可制备出不同组分、不同结构的二氧化锡基纳米纤维。文章综述了具有不同形态结构的均匀型、中空型及多孔型的二氧化锡基纳米纤维的合成及其气敏性能。

Tin oxide nanomaterials have attracted increasing attention due to its excellent physical and chemical properties in the current study. It is an effective method to synthesize tin oxide based nanofibers in order to increase specific surface area, lower working temperature, shorten the response time and recovery time of materials. SnO2 based nanofibers with different components and structures can be prepared by electrospinning,which combined with doping, calcining at high temperature as well as hydrothermal method. The synthesis and gas sensitive properties of SnO2 based nanofibers, which possess different structures including homogeneous,hollow and porous structure,are reviewed in this in the paper.
