ABSTRACT:
An improved metallic catalyst of high surface area is prepared from an alloy comprising a silicon and a second metal which is soluble in oxidizing acids. This alloy is contacted with an oxidizing acid for a time period and at a temperature and acid concentration sufficient to dissolve a portion of the second metal. The alloy is subsequently heated in an atmosphere of inert gas to which a small amount of oxygen is added to convert the silicon at the surface of the alloy to silicon dioxide.
