大牛夏幼南在 MRS-bulletin 上发表的新综述：Shape-controlled synthesis of metal nanocrystals。这篇文章详述了液相制备金属纳米晶以及形貌控制，该文讨论了制备氧化还原反应中的形核和生长。全篇9页，引文50篇。 The ability to control the shape of metal nanocrystals is central to advances in many areas of modern science and technology, including catalysis, plasmonics, electronics, and biomedicine. This article provides a brief overview of our recent efforts toward the development of solution-phase methods for shape-controlled synthesis of metal nanocrystals. While the synthetic methods only involve simple redox reactions, we have been working diligently to understand the complex nucleation and growth mechanisms leading to the formation of metal nanocrystals with desired shapes and related properties. We hope this review will inspire new ideas and concepts in the general area of nanomaterial synthesis, expand our ability to engineer the properties of metals for various applications, and contribute to the realization of sustainable use for some of the scarcest materials. We have to emphasize that our current understanding of most syntheses is far from being able to present an atomistic picture for the evolution pathway from a precursor compound to the fi nal nanocrystal. In a zero-order approach, a typical synthesis can be divided into three distinct steps: nucleation, evolution of nuclei into seeds, and growth of seeds into nanocrystals. While structural fl uctuation between different confi gurations is inherently associated with the nuclei, it is no longer an option for the seeds. As a result, it has been feasible to elucidate the correlations between the seeds and nanocrystals through electron microscopy analysis. However, the evolution from nuclei to different types of seeds remains a black box. Searching for this kind of correlation should continue to be the focus of research in this area.  13.jpg  11.jpg  10.jpg |
