Since the discovery of the role of oxidative etching in shape-controlled metal nanostructure synthesis in 2004, it has become a versatile tool to precisely manipulate the nucleation and growth of metal nanocrystals at the atomic level. Subsequent research has shown that oxidative etching can be used to reshape nanocrystals via atomic addition and subtraction. This research has attracted extensive attention from the community because of its promising practical applications and theoretical value, and as a result, tremendous efforts from numerous research groups have been made to expand and apply this method to their own research. In this review, we first outline the merits of oxidative etching for the controlled synthesis of metal nanocrystals. We then summarize recent progress in the use of oxidative etching to control the morphology of a nanostructure during and after its synthesis, and analyze its specific functions in controlling a variety of nanocrystal parameters. Applications enabled by oxidative etching are also briefly presented to show its practical impact. Finally, we discuss the challenges and opportunities for further development of oxidative etching in nanocrystals synthesis.
自 2004 年发现氧化刻蚀在控制金属纳米结构合成的形状中的作用以来,它已成为一种通用工具,可以在原子水平上精确控制金属纳米晶体的成核和生长。随后的研究表明,氧化刻蚀可用于通过原子的添加和减少来重塑纳米晶体。由于其有前途的实际应用和理论价值,这项研究引起了科学界的广泛关注,因此,许多研究小组都做出了巨大的努力来扩展和应用这种方法到自己的研究中。在这篇综述中,我们首先概述了氧化刻蚀在控制金属纳米晶体合成方面的优点。然后,我们总结了最近在利用氧化刻蚀在纳米结构的合成过程中和之后控制其形态方面的进展,并分析了其在控制各种纳米晶体参数方面的具体功能。简要介绍了氧化刻蚀所带来的应用,以展示其实际影响。最后,我们讨论了氧化刻蚀在纳米晶体合成中进一步发展所面临的挑战和机遇。
