在这篇评论中,我们将向读者介绍使用电置换反应来设计高度可调纳米结构以用于各种应用的最新进展。我们将开始讨论已用于此类反应的各种模板以及结构细节(例如,形状、尺寸和缺陷等)对最终产品具有令人感兴趣的影响,而不仅仅是作为简单的沉积位点。接下来将讨论我们如何操纵合金化和去合金化的过程来产生新的结构,以及前体的类型如何影响最终的性能。最后,将讨论这些材料的有趣的光学性质和在生物医学工程和催化领域的一些创新应用,完成我们对电流替代技术的概述。
In this review, we will bring the reader up to date with recent advances in the use of galvanic replacement reactions to engineer highly tunable nanostructures for a variety of applications. We will begin by discussing the variety of templates that have been used for such reactions and how the structural details (e.g., shape, size, and defects, among others) have interesting effects on the ultimate product, beyond serving as a simple site for deposition. This will be followed by a discussion of how we can manipulate the processes of alloying and dealloying to produce novel structures and how the type of precursor affects the final properties. Finally, the interesting optical properties of these materials and some innovative applications in areas of biomedical engineering and catalysis will be discussed, completing our overview of the state of the art in galvanic replacement.
