Self-Assembly of Copper Oxide Core-Shell Nanowires Through Ethyl Alcohol

摘要: The control of the core-shell structure at nanometer is one most fundamental chal‐ lenges in condensed matter science [Deville et al., 2009; Woodley 2008; Bannin, 2007; Ji Lauhon 2002]. One concepts regarding synthesis nanowires via spontaneous self-organization individual nanoparticles, called spontane‐ ous organization nanocrystals, refers to formation two-dimensional (2-D) and 3-D ar‐ rays nanoparticles or [Tang 2002; Lu Balazs 2006; Tang 2006]. copper-oxide based system, such as Cu2O [Huang 2012; Hong 2011; Yao 2010], CuO [Wu, Cheng Chou 2008], Cu2O@CuO [Yec 2012], has been known facilitate oxidation reactions bulk material, which may al‐ low it be a cost effective substitute for noble metals various catalytic systems. With recent developments nanostructures leading ability size, reproducibility structural complexity [Lauhon Fan 2005], becomes worthwhile possibly paramount define specific target structures on an understanding mechanism mechanism. Upto now, many complex procedures, vapor-liquid-solid, chemical vapor deposition, thermal evaporation, reactions, have developed one-dimension‐ al materials Copper-based nano compounds 2010]. In addition these methods, solution route including solvothermal, hydro‐ thermal, self-assembly, template-assisted deposition become prom‐ ising option large –scale production nanomaterials, due simple, fast, less expensive virtues [Xin Li 1999; 2000; Hung 2004; Roy 2003; Baxter 2003]. However, new type immersing into liquid alcohol
