“…(An fcc form of CuH can be obtained by direct reaction of the elements, but this is only stable above 12.5 GPa.) 20 Route (2) also results in an insoluble form of CuH ("CuH/ [BH 4 ] − "), and in this case the precipitate is coffee-colored 13 rather than the rust-red of route (1) or blood-red of route (3).…”

“…It is unique among the binary metal hydrides in that it can be synthesized in solution, at room temperature. CuH appears in varied circumstances: it is observed as an intermediate phase in the dissolution of brass in sulfuric acid , and electroless copper plating . CuH is proposed as the means by which hydrogen is stored subsurface in Cu/Zn/Al 2 O 3 methanol synthesis catalysts, and it is suggested as a route to copper catalysts .…”

CuH is a material that appears in a wide diversity of circumstances ranging from catalysis to electrochemistry to organic synthesis. There are both aqueous and nonaqueous synthetic routes to CuH, each of which apparently leads to a different product. We developed synthetic methodologies that enable multigram quantities of CuH to be produced by both routes and characterized each product by a combination of spectroscopic, diffraction and computational methods. The results show that, while all methods for the synthesis of CuH result in the same bulk product, the synthetic path taken engenders differing surface properties. The different behaviors of CuH obtained by aqueous and nonaqueous routes can be ascribed to a combination of very different particle size and dissimilar surface termination, namely, bonded hydroxyls for the aqueous routes and a coordinated donor for the nonaqueous routes. This work provides a particularly clear example of how the nature of an adsorbed layer on a nanoparticle surface determines the properties.
