Abstract Better understanding the crystal-facet engineering of a crystal with tailored architecture has demonstrated a significant implication for rational design and synthesis of promising micro-/nanostructure. In the past decades, extensive investigations have been devoted to the development of cuprous oxide (Cu2O) crystals with tailored architectures, which can provide a meritorious platform for not only revealing the structure-property-performance relationship and but also improving the performances in their practical applications. Several previous reviews have mainly reported the partial summaries of the advances in facet-dependent properties of Cu2O crystals. However, a comprehensive summary on Cu2O crystals is lacking and highly desirable to further promote the development of function-oriented Cu2O-based micro-/nanostructures. In this review, we will comprehensively highlight the important progresses in Cu2O crystals with tailored architectures, including the synthetic strategies and corresponding growth mechanisms, the fundamental properties of different crystallographic facets, the functional modifications (including doping and hybridization), and their potential applications. Several urgent issues and perspective are also discussed.

具有定制结构的氧化亚铜 (Cu 2 O) 晶体：对合成、基本特性、功能修饰和应用的全面回顾

摘要 更好地理解具有定制结构的晶体的晶面工程对于合理设计和合成有前景的微/纳米结构具有重要意义。在过去的几十年中，广泛的研究致力于开发具有定制结构的氧化亚铜 (Cu2O) 晶体，这为揭示结构-性能-性能关系以及提高其实际性能提供了一个有价值的平台。应用程序。之前的几篇评论主要报道了 Cu2O 晶体的面相关特性方面的进展的部分总结。然而，缺乏对 Cu2O 晶体的全面总结，并且非常需要进一步促进功能导向的 Cu2O 基微/纳米结构的发展。在这篇综述中，我们将全面强调具有定制结构的 Cu2O 晶体的重要进展，包括合成策略和相应的生长机制、不同晶面的基本特性、功能修饰（包括掺杂和杂化）及其潜在应用。还讨论了几个紧迫的问题和观点。
