Researchers at the University of Rochester developed algorithms that explain how nanoscale catalysts convert propane into propylene. Propylene is a key starting material for products such as plastic squeeze bottles and outdoor furniture. Earlier, a 2021 paper in Science showed that tandem nanoscale catalysts can combine several process steps into a single reaction, improving yield and lowering cost.
The new study, published in the Journal of the American Chemical Society, uses algorithms to identify the atomic features that drive the complex chemistry. The team examined reactions complicated by materials that exist in different states, for example metallic and oxide phases, and applied computational screening to narrow down many possible atomic arrangements.
Siddharth Deshpande and his student Snehitha Srirangam found that the oxide material tends to grow around defective metal sites. This selective growth is important for catalyst stability. The authors say the algorithms and atomic insights could apply to other industrial reactions, such as methanol synthesis, and help companies move away from trial-and-error methods.
