Supported bimetallic nanoparticles used for various chemical transformations appear to be more appealing than their monometallic counterparts, because of their unique properties mainly originating from the synergistic effects between the two different metals. Exsolution, a relatively new preparation method for supported nanoparticles, has earned increasing attention for bimetallic systems in the past decade, not only due to the high stability of the resulting nanoparticles but also for the potential to control key particle properties (size, composition, structure, morphology, etc.). In this review, we summarize the trends and advances on exsolution of bimetallic systems and provide prospects for future studies in this field.
用于各种化学转化的负载型双金属纳米颗粒似乎比其单金属对应物更具吸引力，这是因为它们具有独特的性质，主要源于两种不同金属之间的协同效应。外延生长是一种相对较新的负载型纳米颗粒制备方法，在过去十年中，双金属体系越来越受到关注，这不仅是因为所得纳米颗粒具有高稳定性，还因为有控制关键颗粒性质（尺寸、组成、结构、形态等）的潜力。在本综述中，我们总结了双金属体系外延生长的趋势和进展，并为该领域的未来研究提供了展望。
