What Are the Challenges Associated with Metal Doping?
While metal doping can offer numerous benefits, it also presents several challenges:
1. Uniform Distribution: Achieving a uniform distribution of the dopant metal throughout the catalyst can be difficult. 2. Cost: Some dopant metals, like Pt and Pd, are expensive, which can limit their practical applications. 3. Stability: Ensuring that the dopant metal remains stable and does not leach out during the reaction is crucial for long-term catalyst performance.
