Ag5 nanoclusters with dual catalytic antiradical activities

Ag nanoclusters of 5 atoms, Ag5, synthesized by a kinetic control method, show exceptional catalytic activities for the redox elimination of radicals. Their use as catalytic radical scavengers in industrially relevant processes involving detrimental free radical formation, such as polymer stabilization, is here demonstrated, opening a new class of catalytic antiradicals with many potential industrial and/or biomedical applications.
