Cupric oxide (CuO), having a narrow bandgap of 1.2 eV and a variety of chemophysical properties, is recently attractive in many fields such as energy conversion, optoelectronic devices, and catalyst. Compared with bulk material, the advanced properties of CuO nanostructures have been demonstrated; however, the fact that these materials cannot yet be produced in large scale is an obstacle to realize the potential applications of this material. In this respect, chemical methods seem to be efficient synthesis processes which yield not only large quantities but also high quality and advanced material properties. In this paper, the effect of some general factors on the morphology and properties of CuO nanomaterials prepared by solution methods will be overviewed. In terms of advanced nanostructure synthesis, microwave method in which copper hydroxide nanostructures are produced in the precursor solution and sequentially transformed by microwave into CuO may be considered as a promising method to explore in the near future. This method produces not only large quantities of nanoproducts in a short reaction time of several minutes, but also high quality materials with advanced properties. A brief review on some unique properties and applications of CuO nanostructures will be also presented.
氧化铜（CuO）具有1.2电子伏特的窄带隙以及多种化学物理性质，近来在能量转换、光电器件和催化剂等诸多领域备受关注。与块状材料相比，CuO纳米结构已展现出其优异性能；然而，这些材料尚无法大规模生产这一事实，成为了实现该材料潜在应用的障碍。在这方面，化学方法似乎是高效的合成工艺，不仅能大量生产，还能产出高质量且具有优异性能的材料。本文将概述一些常见因素对通过溶液法制备的CuO纳米材料的形貌和性能的影响。就先进纳米结构的合成而言，微波法可被视为一种在不久的将来值得探索的有前景的方法，该方法在前驱体溶液中生成氢氧化铜纳米结构，随后通过微波依次将其转化为CuO。此方法不仅能在短短几分钟的反应时间内大量生产纳米产物，还能产出具有优异性能的高质量材料。本文还将简要综述CuO纳米结构的一些独特性能及应用。
