There are few environments more aggressive than the hot, gaseous surroundings where catalyst materials are frequently used. These catalysts are very sensitive to temperature and pressure, both of which can affect their performance in products like catalytic converters. So when researchers Shuyi Zhang of the University of Michigan, and Dr. George Graham, a 20-year Ford Motor Company veteran, wanted to investigate the underlying chemical reactions of a Pd/TiO2 catalyst at atomic resolution, they needed a tool capable of withstanding the aggressive environments that also delivered atomic resolution images.
In an upcoming Materials Today webinar, on August 18th, you can learn how the researchers used the Atmosphere gas cell system to directly observe catalyst structure evolution in realistic environments. Their work, published in Nano Letters, marked the first time that this type of catalysis was performed and imaged at atomic resolution within the TEM column. The webinar will highlight some of their key findings, such as the amorphous to crystalline transition of the TiOx shieling layer that inhibits the performance of the Pd nanoparticle catalysts. Dr. Graham will also provide his insights into how in situ gas cell TEM is positioned to become a vital tool for future catalysis research, both in industry and in academia. The webinar will conclude with a live Q&A session and is completely free to attend.
