How Does Iridium Compare to Other Transition Metals in Catalysis?
Iridium generally provides superior performance in specific reactions compared to other transition metals like platinum or palladium. For instance, in the hydrogenation of unsaturated hydrocarbons, iridium displays higher activity and selectivity, often resulting in enhanced reaction rates and product yields. However, the high cost and limited availability of iridium can be a drawback when compared to more abundant metals.
