Synthesis of efficient Vulcan-LaMnO3 perovskite nanocomposite for the oxygen reduction reaction

In situ autocombustion has been developed as a novel and efficient route for the synthesis of perovskite-carbon nanocomposites for the oxygen reduction reaction (ORR) in alkaline media. We demonstrate the synthesis of crystalline LaMnO3 + δ perovskite-Vulcan composite with a high accessibility of active sites and high electronic conductivity required for efficient electrocatalysis. The rotating disc electrode measurements evidenced an excellent activity of the composite for the ORR.
