How the Surface Structure Determines the Properties of CuH

CuH occurs in fields ranging from catalysis to electrochemistry to organic synthesis. We show that, while both aqueous and nonaqueous methods for the synthesis of CuH result in the same bulk product, the surface properties differ: bonded hydroxyls from aqueous routes and a coordinated donor from nonaqueous routes. This work provides a particularly clear example of how the nature of an adsorbed layer on a nanoparticle surface determines the properties
