Hydrogen interaction with gold

So far, we have only discussed the reactivity of monometallic wires further. Because of the wide range of possibilities for the adsorption, the study of hydrogen interaction with bimetallic wires is much more complicated. However, it is interesting to examine some aspects that give us a better understanding of the nature of the bond between hydrogen and nanowires. Due to their stability, the most important and illustrative cases are the gold bimetallic wires Au p2 and Au ,P5, where p correspond to copper or silver atoms. 

Oxidations of the two molecules appear to proceed almost but perhaps not quite wholly independently of each other the dissociative chemisorption of hydrogen is not much affected by the carbon monoxide, which, in view of what was said in Chapter 5, is somewhat surprising, as there it seemed that both interacted with lowly coordinated gold atoms. The dependence of kinetic parameters on the hydrogen concentration has not been... 

Aurous cyanide forms yellow, microscopic laminae, very slightly soluble in Water. It is more stable than aurous iodide, but at red heat is decomposed into gold and cyanogen. Its insolubility renders it immune to the action of dilute acids and hydrogen sulphide, but solutions of ammonia, potassium hydroxide, ammonium sulphide, and sodium thiosulphate dissolve it, probably forming complex derivatives. In aurous cyanide the tendency to form complex compounds is much more marked than in the corresponding chloride, bromide, and iodide.3 Its interaction with potassium ferrocyanide has been studied by Beutel.4...
