Large-Scale Synthesis of Single-Crystalline Quasi-Aligned Submicrometer CuO Ribbons

Abstract

A new strategy of scrolling a lamellar precursor was designed to form a ribbonlike structure. In a simple chemical route involving an oxidation−dehydration process, single-crystalline quasi-aligned submicrometer CuO ribbons were synthesized on a copper surface. Electron microscopic studies indicate that these ribbons have a width of around 250 nm and length of up to 5 μm.
