Claims21
A reagent suitable for use as a catalyst comprising:
- a first metal species substrate having a second reduced metal species coated thereon, the second reduced metal species being less electropositive than the first metal wherein the second metal reduced species comprises from about 0.1% to about 1% of the reagent by weight and further wherein the second metal reduced species is disposed on the first metal in a form selected from the group consisting of islands, spots, lines, dashes, weave form, or pattern form.
A method of making a reagent comprising:
- a. providing a substrate comprising a first metal;
- and
- b. applying a second metal less electropositive than the metal of the first metal onto the substrate,
- wherein the second metal is reduced to form a second metal reduced species and further Wherein the second metal comprises from about 0.1 % to about 1% of the reagent by weight and further wherein the second metal reduced species is disposed on the first metal in a form selected from the group consisting of islands, spots, lines, dashes, weave form, or pattern form.
A method of making a reagent comprising refluxing a metal substrate in the presence of a metal salt and a solvent, wherein the metal salt comprises a metal less electropositive than the metal of the substrate and further wherein the metal of the metal salt comprises 1% or less of the reagent by weight and the metal of the metal salt is disposed on the metal substrate in a form selected from the group consisting of islands, spots, lines, dashes, weave form, or pattern form.
