1 Results Strongly disordered metals with the high chemical and catalytic activity are often called as skeletal metals.Usually for their preparation the metallides of d-metal (which afterwards will be left in the “skeleton”) and chemically active component(s) are firstly synthesized.Then the last one(s) is (are) removed by the leaching with aqueous solutions of alkalis or carbonates.However,this method sometime fails,first of all,for the reactions,which should be realized in non-aqueous conditions.In the present work a “dry” way of the activated metals making,based on the method of selective vapor transporting reactions (SVTR) has been considered.The main idea of this method is the removal of the active component from a metallide to the vapor phase.For instance: 1 Results Strongly disordered metals with the high chemical and catalytic activity are often called as skeletal metals.
