Sintering and leaching of supported base-metal catalysts are eliminated by atomic layer deposition (ALD) overcoating during liquid-phase reactions, as demonstrated by operando x-ray adsorption spectroscopy. Furthermore, the acid/base properties of these catalysts can be tuned by the atomically precise ALD synthesis providing control over the functionality of the stabilizing overcoat.
