Fritz Haber Institute - Catalyst Nanoparticles Redox

This in situ TEM video clearly visualises the structure dynamics of the Ni catalyst particle oscillating through three stages of the catalytic reaction process - (1) activation, (2) the working state under reaction conditions and (3) recovery from the working state to its initial state. The drastic morphological change suggests that the cycle variation may not only be limited to the surface structure, however, takes place throughout the entire particle. Although little modelling has been identified which support such dynamics in metal catalysts, it highlights that using in situ TEM techniques for catalyst research can reveal unexpected and exciting scientific phenomenon.

Very beautiful video!
Is there any information about this video? It is published somewhere, what kind of metal was used?

Thank you for your comment, Ilia! I have just updated the video description to include all the information about this video. The metal used was Nickel.
