Carbon-supported Pt-Co catalyst for the oxygen reduction reaction was covered with silica layers to inhibit sintering of the metal particles. Coverage of the Pt-Co catalyst with silica layers promoted the formation of alloys with small diameters during treatment at 973 K. The silica-coated Pt-Co electrocatalyst showed a large electrochemically active surface area (ECSA) and excellent durability.
