Electrocatalyst, with method of making and systems including the electrocatalyst

A method for making a bi-metallic electrocatalyst, comprising:

• adding, to a water solution, a first organometallic compound, nAR1x;
• adding, to the water solution, a second organometallic compound mBR2y in a ratio m/n to the first organometallic compound;
• adding, to the water solution, a quantity of catalyst support particles;
• creating a condition in the water solution for at least a portion of the metals A, B to:
• dissociate from their respective ligands R1, R2,
• associate with a hydroxide counter ion to form metal hydroxides A(OH)x and B(OH)y,
• adhere the metal hydroxides to the catalyst support particles as an intermediate catalyst and catalyst support complex, and
• precipitate the intermediate catalyst and catalyst support complex out of solution as a catalyst precipitate complex;
• drying the catalyst precipitate complex;
• and
• calcining the catalyst precipitate complex to convert the metal hydroxides to crystalline metal oxides disposed on the support particles, the crystalline metal oxides comprising two non-platinum group metal oxides in crystalline form;
• wherein:
• A is a first metal selected from the group consisting of manganese, cobalt, nickel, iron, chromium, titanium, vanadium, niobium, silver and copper;
• B is a second metal, different from the first metal, selected from the group consisting of manganese, cobalt, nickel, iron, chromium, titanium, vanadium, niobium, lanthanum, strontium, lithium, silver and copper;
• R1 is a ligand associated with the first metal;
• R2 is a ligand associated with the second metal;
• x is equal to an oxidation state of the first metal;
• y is equal to an oxidation state of the second metal;
• and
• 0.01<m/n<30.
