DENSsolutions welcome you to watch their 1st user webinar, with a presentation from Dr Marc Willinger, a Climate user:
“In my presentation, I will highlight the importance of in situ electron microscopy for catalysis, and share some of the experience we have collected over the years. I will show how we apply a combination of in situ TEM and in situ SEM, to study the dynamics of active catalysts under simple redox conditions as well as under industrially relevant reactions, such as methanol oxidation. By bridging the scale from the Å to the mm range and pressures from 10-5 to 10+5 Pa, we are able to reveal the dynamic nature of active catalysts and to bridge the materials and pressure gap between simplified model systems and real-world catalysis. It will be shown that simultaneous detection of reaction products by RGA enables correlating structural dynamics with catalytic activity. We observe rate oscillations and oscillatory behaviour that is inherent to the action of a catalyst, which has to break bonds and facilitate the formation of new ones over and over again.”
