We report a green synthesis of Cu(2)O nanowires and nanotubes in aqueous solution by reducing Cu(2+) to Cu(+) with glucose or fructose via Fehling's reaction. The screw dislocation-driven growth of Cu(2)O nanowires and nanotubes is confirmed by imaging the dislocation contrast, the Eshelby twist associated with dislocations and the spontaneously formed hollow nanotubes.
我们报告了一种在水溶液中通过费林反应将 Cu(2+)还原为 Cu(+)，从而用葡萄糖或果糖绿色合成 Cu(2)O 纳米线和纳米管的方法。通过成像位错对比、与位错相关的埃舍尔扭曲和自发形成的中空纳米管，证实了 Cu(2)O 纳米线和纳米管的螺旋位错驱动生长。
