Abstract

Read online

Smaller nanostructures often have higher activities, but at the expense of losing chemical stability. Here, the authors find that reducing the size of FeO nanostructures to below 3 nm enhances their resistance to oxidation, and attribute this unexpected observation to a size-dependent, structural dynamics effect.
