Boron nitride nanoribbons (BNNRs), the boron nitride structural equivalent of graphene nanoribbons (GNRs), are predicted to possess unique electronic and magnetic properties. We report the synthesis of BNNRs through the potassium-intercalation-induced longitudinal splitting of boron nitride nanotubes (BNNTs). This facile, scalable synthesis results in narrow (down to 20 nm), few sheet (typically 2-10), high crystallinity BNNRs with very uniform widths. The BNNRs are at least 1 μm in length with minimal defects within the ribbon plane and along the ribbon edges.
氮化硼纳米带（BNNRs）是氮化硼结构的等效物，与石墨烯纳米带（GNRs）类似，被预测具有独特的电子和磁性质。我们通过钾插层诱导的氮化硼纳米管（BNNTs）的纵向分裂来合成 BNNRs。这种简便、可扩展的合成方法得到了窄（低至 20nm）、少层（通常为 2-10 层）、高结晶度的 BNNRs，其宽度非常均匀。BNNRs 的长度至少为 1μm，在带平面内和沿带边缘的缺陷最小。
