Abstract:
1. A method of making porous, dendritic, elemental platinum tubes, the method comprising: forming an aqueous solution of platinum cations, the solution being formed with an amount of the platinum cations and at a temperature; adding dendritic particles of an elemental second metal to the solution, the dendritic particles of the elemental second metal having a greater reduction potential than the platinum cations, the amount of platinum cations being such that dendritic particles of the elemental second metal are dissolved and a portion of the amount of platinum cations are precipitated as porous, hollow, dendritic tubes of elemental platinum; the temperature of the solution, the amount of platinum cations, and the selection of the second elemental metal producing the porous dendritic platinum tubes; and separating the porous dendritic platinum tubes from the solution.
