摘要

在这项工作中，通过改变合成后处理和气相生长，引入了接枝羟基（OH）基团对二氧化锡纳米线的功能化。此外，本文还介绍了两种生长方法：(i) 在不同 pH 值的 NaOH 溶液中进行合成后处理的气固生长法；(ii) 在水蒸气中直接使用气液固生长法。结构表征表明，羟基被成功锚定。值得注意的是，带隙在羟基的存在下发生了变化。这种表面状态工程恰恰为二氧化锡纳米线在传感器和半导体领域的应用开辟了新的途径。

Surface modification of tin oxide nanowires through hydroxyl group anchoring

In this work, the functionalization of SnO₂ nanowires with grafted hydroxyl (OH) groups was introduced by changing the post-synthetic treatment and by growth in a vapor phase. Besides, the present paper describes two types of growth methods: (i) the vapor–solid one with post-synthesis treatment under NaOH solutions with different pH, and (ii) the direct growth using the vapor–liquid–solid one under water vapor. Structural characterizations demonstrated that OH groups were successfully anchored. Notably, band gap changes in the presence of OH groups are revealed. This kind of surface state engineering precisely opens new avenues of SnO₂ nanowire applications in sensors and semiconductor uses.
