Article Synopsis
- Silver nanoclusters (5 Ag atoms) show high efficiency in deactivating radicals, demonstrating catalytic activity up to 4 orders of magnitude greater than typical systems when tested with the DPPH radical.
- They remain stable post-reaction, allowing for repeated use as anti-radical catalysts by oxidizing methanol to formaldehyde—a process supported by DFT calculations.
- These nanoclusters not only help reduce radicals but also promote decomposition of hydrocarbons, potentially offering new methods for preventing polymer degradation in industrial applications.
Synthesis and purification of metal clusters without strong binding agents by wet chemical methods are very attractive for their potential applications in many research areas. However, especially challenging is the separation of uncharged clusters with only a few number of atoms, which renders the usual techniques very difficult to apply. Herein, we report the first efficient separation of Ag and Ag clusters using the different entropic driving forces when such clusters interact with DNA, into which Ag selectively intercalates.
