Effect of gold oxidation state on the epoxidation and hydrogenation of propylene on Au/TS-1

Treatment of gold samples supported on TS-1 with sodium cyanide solutions resulted in the precipitation of gold (I) cyanide. When this occurred, the selectivity of the reaction of propylene with hydrogen and oxygen mixtures shifted from propylene oxide to propylene, a selectivity characteristic of P...
