Patent ID: 8691716

Claim:
A method for making anodic electrocatalysts configured to oxidize fuel and/or cathodic electrocatalysts configured to reduce oxygen for use in polymer electrolyte membrane fuel cells and direct methanol fuel cells and H 2 electrogenerators, the method comprising the step of synthesizing materials having a controlled metallic composition based on mono- and plurimetallic carbon nitrides, wherein the synthesizing step comprises the steps of: preparing a precursor; applying a suitable thermal treatment to the precursor; and activating the electrocatalysts; wherein the precursor is prepared through sol-gel reactions through steps comprising: generating a solution A, wherein solution A comprises either water or an organic solvent, an organic binder and at least one complex containing a transition metal coordinated by halides; generating a solution B, wherein solution B comprises water, an organic binder and at least one cyanometallate; and mixing solution A and solution B.
