Depiction of the experimental setup where palladium nanorods lie atop gold nanobars. In this image, an electron beam is directed at the sample to watch the catalytic interactions between the hydrogen molecules (in green) and the palladium catalyst. The light driving the illumination is shown in red. (Image credit: Katherine Sytwu)

In this image, an electron beam is directed at the sample to watch the catalytic interactions between the hydrogen molecules ( in green ) and the palladium catalyst. The light driving the illumination is shown in red. (Image credit: Katherine Sytwu) Using state-of-the-art fabrication and imaging, researchers watched the consequences of adding sculpted light to a catalyst during a chemical transformation. This work could inform more efficient - and potentially new - forms of catalysis. Like a person breaking up a cat fight, the role of catalysts in a chemical reaction is to hurry up the process - and come out of it intact. And, just as not every house in a neighborhood has someone willing to intervene in such a battle, not every part of a catalyst participates in the reaction.
