25th Anniversary Article: Galvanic Replacement: A Simple and Versatile Route to Hollow Nanostructures with Tunable and Well Controlled Properties
這篇綜述是夏幼南組發(fā)表在Adv. Mater.25周年的一篇文章,主要討論了伽爾瓦尼還原反應在合成復雜的空心納米結構方面的應用及進展。文章首先說明了伽爾瓦尼還原反應的機理,強調了它在控制金屬納米結構的尺寸、成分、結構、形狀、形貌等方面的能力,然后討論了伽爾瓦尼還原反應過程中的一些概念,例如面選擇性,合金化的影響等。同時也說明了如何將伽爾瓦尼還原反應與共還原、柯肯特爾效應結合起來合成復雜的納米結構,最后強調了伽爾瓦尼還原反應在催化、等離子體、生物醫(yī)藥方面的應用以及發(fā)展前景。希望對大家有所幫助。
This article provides a progress report on the use of galvanic replacement for generating complex hollow nanostructures with tunable and well controlled properties. We begin with a brief account of the mechanistic understanding of galvanic replacement, specifically focused on its ability to engineer the properties of metal nanostructures in terms of size, composition, structure, shape, and morphology. We then discuss a number of important concepts involved in galvanic replacement, including the facet selectivity involved in the dissolution and deposition of metals, the impacts of alloying and dealloying on the structure and morphology of the final products, and methods for promoting or preventing a galvanic replacement reaction. We also illustrate how the capability of galvanic replacement can be enhanced to fabricate nanomaterials with complex structures and/or compositions by coupling with other processes such as coreduction and the Kirkendall effect. Finally, we highlight the use of such novel metal nanostructures fabricated via galvanic replacement for applications ranging from catalysis to plasmonics and biomedical research, and conclude with remarks on prospective future directions.![Adv.
