Copper oxide nanowires (CuO NWs) were synthesized by thermally oxidizing copper foils at various heating rates. It has been shown that both monoclinic CuO and cubic Cu2O phases were grown on the copper surface with NW diameters of almost 200 nm for all samples. While NWs were shown to be dense for low heating rates, they end up being broken for quick heating. The underlying growth mechanism was described basing on a detailed comprehensive study, and the effect of the heating rate was explained by considering the thermal shock effect and in-plane tensile stresses on curved surfaces. This study contributes to the research for suitable methods for the use of recyclable metals in technological applications. In particular, copper oxide NWs were deposited, for the first time, on FTO/glass substrates, and the optical characterization revealed that this method is a promising way to improve the surface contact for solar cells and catalytic applications.

一种控制用于太阳能电池和催化应用的氧化铜纳米线生长的简单方法

氧化铜纳米线(CuO NWs)是通过在不同的加热速率下对铜箔进行热氧化来合成的。已经表明,对于所有样品,单斜 CuO 和立方 Cu2O 相都生长在铜表面上,NW 直径几乎为 200 nm。虽然 NW 被证明在低加热速率下是致密的,但它们最终会因快速加热而被破坏。基于详细的综合研究描述了潜在的生长机制,并通过考虑曲面上的热冲击效应和面内拉伸应力来解释加热速率的影响。这项研究有助于研究在技术应用中使用可回收金属的合适方法。特别是,第一次将氧化铜 NW 沉积在 FTO/玻璃基板上,
