What are the Challenges Associated with Noble Metal Nanocrystals?
Despite their benefits, there are challenges associated with noble metal nanocrystals: - Cost: Noble metals are expensive, making the large-scale application of these nanocrystals costly. - Stability: Nanocrystals can agglomerate or undergo sintering, leading to a loss of catalytic activity. - Selective Catalysis: Achieving high selectivity for desired reactions while minimizing by-products can be challenging.
