What are the Challenges Associated with Metal Nanoparticles in Catalysis?
Despite their advantages, metal nanoparticles face several challenges, such as:
Aggregation: Nanoparticles tend to aggregate, reducing their effective surface area and catalytic activity. Stability: Metal nanoparticles can undergo oxidation or other forms of degradation over time, affecting their performance. Cost: Some metal nanoparticles, such as those made from platinum or palladium, can be expensive to produce.
