Why is nanoparticle stability important in catalysis?
Stability is crucial for maintaining the catalytic activity over time. Unstable nanoparticles can undergo:
Aggregation, leading to a decrease in surface area and catalytic activity. Sintering, resulting in the growth of larger particles which are less effective. Leaching, where active metal components dissolve into the reaction medium, leading to a loss of catalytic material.
Ensuring stability helps in achieving consistent performance, longevity, and cost-effectiveness.
