Patent ID: 7776197

Claim:
A method for electroplating an electrode surface coating having a high surface area, the method comprising: dissolving sodium dihydrogen phosphate and disodium hydrogen phosphate in deionized water to form a phosphate solution; adding palladium chloride to the phosphate solution to form a plating solution; providing a three-electrode reaction cell comprising a plating electrode, a common electrode, and a reference electrode; placing the plating solution in the three-electrode reaction cell; additionally providing one or more substrates in electrical communication with the common electrode to be coated by electroplating; placing said one or more substrates in the plating solution of the reaction cell; applying voltage to the reaction cell to form a palladium surface coating having a high surface area on said one or more substrates, wherein said palladium surface coating provides an electrochemically active surface increase of about 10 times to the one or more substrates and said palladium surface coating has a thickness of about 1.0 μM.
