Using pictures with atomic resolution, the mechanism of an important chemical reaction has finally be explained: When platinum nanoparticles act as catalysts on an iron oxide surface, the surface plays a crucial role.
Scientists have used first-principles computer simulations to explain why small platinum nanoparticles are less effective catalysts than larger ones.
Chemists embed metallic nanoparticles into laser-induced graphene, turning it into a useful catalyst for fuel cell and other applications.
A new fabrication technique that produces platinum hollow nanocages with ultra-thin walls could dramatically reduce the amount of the costly metal needed to provide catalytic activity in such applications as fuel cells.
