Operando Transmission Electron Microscopy of Noble Metal Nano-catalysts During CO Oxidation

Metal nanoparticles are common catalyst materials for a broad range of chemical reactions in industry.However, the current challenge in optimizing the performance of these nanoparticle catalysts is that we have limited insights into the "working state" of these materials.Nano-catalysts commonly re-structure under reaction conditions and their catalytic performance is determined by these dynamical structures.Conventional high-resolution characterization techniques cannot probe these structures because they typically require a vacuum environment.Hence, significant research has been invested into extending these techniques towards in situ or operando characterization [1].
