What are the Challenges Associated with Noble Metal Catalysts?
Despite their effectiveness, the use of noble metals in catalysis comes with several challenges:
Cost: Noble metals are rare and expensive, which can significantly increase the overall cost of catalytic processes. Scarcity: Limited availability of these metals can pose supply chain risks. Deactivation: Although resistant to oxidation, noble metal catalysts can still deactivate over time due to sintering, poisoning, or fouling.
