Despite its advantages, Pd/C does have some limitations: - Cost: Palladium is an expensive metal, which can increase the overall cost of the catalytic process. - Leaching: In some reactions, palladium can leach from the carbon support, leading to contamination of the product and loss of catalyst. - Sensitivity to Poisons: Pd/C can be sensitive to catalyst poisons such as sulfur and nitrogen compounds, which can deactivate the catalyst.
