What Challenges Are Associated with Platinum Catalysts?
Despite its effectiveness, the use of platinum in catalysis presents several challenges. The most significant is its high cost, driven by its scarcity and the complex processes involved in its extraction and refining. Additionally, platinum catalysts can suffer from poisoning, where impurities in the reactants bind to the platinum surface, inhibiting its catalytic activity. This necessitates the development of strategies to regenerate or replace poisoned catalysts, which can be both technically challenging and costly.
