Abstract

Metal oxide nanowires (NWs) with a high surface area, ease of fabrication, and precise control over diameter and chemical composition are among the best candidates for the realization of resistive gas sensors. Among the different techniques used for the synthesis of materials with NW morphology, approaches based on the vapor-liquid-solid (VLS) mechanism are very popular due to the ease of synthesis, low price of starting materials, and possibility of branching. In this review article, we discuss the gas-sensing features of metal oxide NWs grown by the VLS mechanism, with emphasis on the growth conditions and sensing mechanism. The growth and sensing performance of SnO, ZnO, InO, NiO, CuO, and WO materials with NW morphology are discussed. The effects of the catalyst type, growth temperature, and other variables on the morphology and gas-sensing performance of NWs are discussed.

摘要

具有高表面积、易于制造且能精确控制直径和化学成分的金属氧化物纳米线（NWs）是实现电阻式气体传感器的最佳候选材料之一。在用于合成具有NW形态材料的不同技术中，基于气-液-固（VLS）机制的方法非常受欢迎，这是因为其合成简便、起始材料价格低廉且具有分支的可能性。在这篇综述文章中，我们讨论了通过VLS机制生长的金属氧化物NWs的气敏特性，重点关注生长条件和传感机制。还讨论了具有NW形态的SnO、ZnO、InO、NiO、CuO和WO材料的生长及传感性能。探讨了催化剂类型、生长温度和其他变量对NWs形态和气敏性能的影响。
