Electrochemically active composition, methods of making, and uses thereof
View Patent ↗Accordingly, in various embodiments, the present invention provides methods for making electrochemically active materials. Methods include making an electrochemically active material by reacting a platinum group metal salt in a organic solvent to yield a mixture, then heating the mixture to create a metal-organic solvent complex and an acid, followed by removing at least a portion of the acid, and yielding an electrochemically active material comprising the metal-organic solvent complex. In an exemplary embodiment, the resulting electrochemically active material may be used for coating an electrode.
1. A method of making an electrode, the method comprising:
coating at least a portion of a conductive substrate with a mixture comprising an iridium-methylethylketone complex, tantalum, and a solvent;
heating said conductive substrate coated with said mixture; and
oxidizing said iridium into at least one of an amorphous phase, a crystalline phase, and combinations thereof.
2. The method according to claim 1 , further comprising coupling said conductive substrate to at least one conductive rod.
3. The method according to claim 2 , further comprising attaching said at least one conductive rod to a hanger bar.
4. The method according to claim 1 , further comprising vaporizing essentially all of said methylethylketone.
5. The method according to claim 1 , wherein said heating said conductive substrate coated with said mixture is to a temperature between about 450° C. and about 550° C.
6. The method according to claim 1 , wherein said heating said conductive substrate coated with said mixture is to a temperature between about 360° C. and about 440° C.
7. A method of making an electrode, the method comprising:
