Non-noble metal nanocrystals with well-defined shapes have been attracting increasingly more attention in the last decade as potential alternatives to noble metals, by virtue of their Earth abundance combined with intriguing physical and chemical properties relevant for both fundamental studies and technological applications. Nevertheless, their synthesis is still primitive when compared to noble metals. In this contribution, we focus on the third row transition metals, Mn, Fe, Co, Ni and Cu, that are recently gaining interest because of their catalytic properties. Along with providing an overview on the state-of-the-art, we discuss current synthetic strategies and challenges. Finally, we propose future directions to advance the synthetic development of shape-controlled non-noble metal nanocrystals in the upcoming years.

通过胶体化学塑造非贵金属纳米晶体

在过去的十年中，具有明确形状的非贵金属纳米晶体作为贵金属的潜在替代品越来越受到人们的关注，因为它们在地球上的丰富程度以及与基础研究和技术应用相关的有趣的物理和化学性质。然而，与贵金属相比，它们的合成仍然很原始。在这篇文章中，我们重点关注第三行过渡金属，即锰、铁、钴、镍和铜，它们最近因其催化特性而引起人们的兴趣。除了提供最先进的概述外，我们还讨论了当前的综合策略和挑战。最后，我们提出了未来几年推进形状控制非贵金属纳米晶体合成开发的未来方向。
