[font size=3]Catalysts are everywhere. They make chemical reactions that normally occur at extremely high temperatures and pressures possible within factories, cars and the comparatively balmy conditions within the human body. Developing better catalysts, however, is mainly a hit-or-miss process.
Now, a study by researchers at the University of Pennsylvania, the University of Trieste and Brookhaven National Laboratory has shown a way to precisely design the active elements of a certain class of catalysts, showing which parameters are most critical for improving performance.
…
More than showing a path to improving this particular reaction, the study represents a new way of studying catalytic reactions in general, as well as a more straight-forward way of designing the materials at their core.
“We’re flipping the vision of catalysis,” Cargnello said.” Usually, people see that a material performs well, then study its structure to determine why it behaves the way it does. Here, we’re preparing the structure based on how we think the material is going to be behave, then see how it performs.”
