Abstract

Catalyzing concept: Methyl halides have been used to disperse large (around 20 nm) gold nanoparticles supported on carbon into dispersed gold atoms/dimers at low temperature and atmospheric pressure (see picture). The process occurs through the progressive removal of gold-halogen entities from the metal nanoparticles and a gradual decrease in the size of the gold nanoparticles on the minute timescale.
