Abstract

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.
