New chemical catalysts are less expensive, but more stable

New chemical catalysts are less expensive, but more stable

The Yale University chemists helped develop seven new chemical catalysts that are expected to reduce costs and increase the sustainability of the production of chemical compounds used in a number of industries.

New catalysts are based on palladium, a rare and expensive metal. Palladium catalysts are used to form a number of chemical compounds in pharmaceutical preparations, plastics, agrochemicals and many other industries. Researchers describe the new technology in an article published on May 18 in the journal ACS Catalysis.

«We have developed an improved system that is less susceptible to decontamination and should make most industrial compounds more competitive and sustainable, which can lead to new methods of preparing important compounds», said Nilay Hazari, adjunct professor of chemistry Yale and co-author of the study.

This discovery is based on the previous work of the Khazari group, which identified problems in another catalytic palladium system. First of all, these problems are associated with deactivation of the catalyst.

In fact, the new system creates the best chemical infrastructure on which catalysis can occur. This means that the process requires less palladium, which lowers the cost. The new catalysts are already commercially available from a number of different chemical companies and are likely to be used in the near future for the production of important chemical compounds.
