The potential industrial applications are broad, ranging from the manufacture of medicines to plastics." Edited by Namachieli 04/16/2012 5:13 pm Report this Post to the Staff

Ed_B Pillar of the Community United States 4008 Posts	Posted 04/16/2012 7:36 pm Sounds like an interesting addition to the world of organo-metallic synthesis. It will be even more interesting to see if they can come up with some really useful applications for this new catalyst. If they or others do, it could boost the demand for and price of Pd.

Even 200 years after the elements were discovered, we're still finding new uses for them. Don't say "infinitely" when you mean "very"; otherwise, you'll have no word left when you want to talk about something really infinite. - C. S. Lewis Report this Post to the Staff

Indeed we are and this is likely to continue. When I was doing chemistry for a living, I preferred nickel, palladium, and platinum catalysts that were finely divided and absorbed onto sponge carbon, diatomaceous earth, clay, or some other substrate. It always amazed me that so little of these metals could make such a huge difference in reaction efficiency. By having these catalysts on a substrate of some sort, it became possible to have excellent reactant contact and ease of recovery via filtration. Using expensive catalysts is fine in an industrial setting, as long as you can get good recovery for reuse and recycle. That really holds the cost down while still providing some very nice benefits in reaction efficiency and selectivity. Report this Post to the Staff
