Herein, the dynamics of oxidative etching of Ag nanoparticles in an ionic liquid is monitored in situ via graphene liquid cell transmission electron microscopy. The results reveal that hollow nanosphere formation occurs via a stepwise process involving shell formation and hollowing of the nanoparticle. In addition, we describe the different etching kinetics in each step.
在此，通过石墨烯液体池透射电子显微镜原位监测离子液体中银纳米颗粒的氧化蚀刻动力学。结果表明，空心纳米球的形成是一个逐步的过程，包括纳米颗粒的壳层形成和中空化。此外，我们描述了每个步骤中不同的蚀刻动力学。
