摘要

利用水热生长的脉冲温度，实现了Moo3纳米带向高表面缺陷Moo3纳米纤维的转化。采用场发射扫描电镜(FESEM)、x射线衍射(XRD)、透射电镜(TEM)、高分辨率透射电镜(HR-TEM)和氮吸附-脱附技术对moo3纳米带和纳米纤维进行了表征。结果表明，与Moo3纳米带相比，Moo3纳米纤维具有高结晶性、低厚度、高表面积和高表面缺陷的特点。此外，研究了这些M003纳米带和Moo3纳米纤维的乙醇传感性能，其中Moo3纳米纤维由于Moo3纳米纤维的上述优点而表现出更优越的乙醇传感性能。

Defect Control in MoO3 Nanostructures as Ethanol Sensor

Transformation of Moo3nanobelts into Moo3 nanofibers with high surface defect has been achieved by the application of pulsed temperature during hydrothermal growth. Moo3nanobelts and nanofibers are characterized by field emission scanning electron microscopy (FESEM), x-ray diffraction (XRD), transmission electron microscopy (TEM), high-resolution transmission electron microscopy (HR-TEM), and surface area analysis by nitrogen adsorption-desorption technique. Results clearly revealed that high crystalline, lower thickness, high surface area, and high surface defects are present in the Moo3 nanofibers as compare to Moo3 nanobelts. Furthermore, ethanol sensing properties of these M003 nanobelts and Moo3 nanofibers were examined, where Moo3 nanofibers show superior ethanol sensing properties due to the above mention advantages in Moo3 nanofibers.
