Black phosphorous (BP) flakes are nanostructured via electrochemical intercalation of Na.sup.+ ions into bundles of phosphorene nanoribbons (PNRs). The large diffusion barrier of Na.sup.+ ions along the armchair direction leads to a well-defined columnar intercalation of Na.sup.+ ions in BP, resulting in the long zigzag-oriented columns of disordered material. The sonication of the bundles is then used to separate the PNRs.
