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+delta 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. (C) 2014 Elsevier B.V. All rights reserved.
