摘要

SnO(2)/α-MoO(3)异质结构纳米带实现了极高灵敏度和低工作温度的气体传感器。在300℃的工作温度下，它们对500ppm乙醇的灵敏度高达67.76，高于裸α-MoO(3)和SnO(2)纳米结构。工作温度可低至120℃。这些行为归因于SnO(2)/α-MoO(3)界面结势垒的变化。本研究结果表明，异质结构一维纳米材料可以产生具有改进特性的气体传感器，并且可以应用于广泛的气体传感器。

Enhanced gas sensing performance of SnO2/α-MoO3 heterostructure nanobelts.

Extremely high sensitivity and low working temperature of gas sensors are realized from SnO(2)/α-MoO(3) heterostructure nanobelts. Their sensitivity against 500 ppm ethanol is up to 67.76 at the working temperature of 300 °C, which is higher than that of bare α-MoO(3) and SnO(2) nanostructures. Also the working temperature can be lowered down to 120 °C. Such behaviors are attributed to the variation of the junction barrier at the SnO(2)/α-MoO(3) interface. The present results imply that heterostructured 1D nanomaterials may yield gas sensors with improved characteristics, and can be applied to a wide range of gas sensors.

期刊介绍： The journal aims to publish papers at the forefront of nanoscale science and technology and especially those of an interdisciplinary nature. Here, nanotechnology is taken to include the ability to individually address, control, and modify structures, materials and devices with nanometre precision, and the synthesis of such structures into systems of micro- and macroscopic dimensions such as MEMS based devices. It encompasses the understanding of the fundamental physics, chemistry, biology and technology of nanometre-scale objects and how such objects can be used in the areas of computation, sensors, nanostructured materials and nano-biotechnology.
