STEM Reveals How Gases Can Influence Nanoparticle Structures

Gold-palladium (Au-Pd) nanoparticles are used in various industrial applications as nanocatalysts. However, the adsorption of different gases can cause small changes to the composition of nanocatalysts, affecting their chemical characteristics. Developing a novel method for analyzing these structural changes in Au-Pd nanoparticles is critical for improving their catalytic performance.
