Abstract

Boron nitride nanoribbons (BNNRs) have very attractive electrical and optical properties due to their unique edge states and width-related properties. Herein, for the first time, BNNRs were produced by a simple reflux of boron nitride nanotubes (BNNTs) in nitric acid containing water, which had led to unzipped sidewalls through hydrolysis. Their high reactivity that originated from edges was verified via a strong interaction with methylene blue.

摘要

氮化硼纳米带（BNNRs）因其独特的边缘态和与宽度相关的特性而具有非常吸引人的电学和光学性质。在此，首次通过将氮化硼纳米管（BNNTs）在含水硝酸中简单回流制备出了BNNRs，这通过水解导致了侧壁的打开。通过与亚甲基蓝的强相互作用验证了其源自边缘的高反应活性。
