The Research of Mn Modified Carbon Sphere Supported Pt Catalyst Material for Direct Methanol Fuel Cell

Mn modified carbon sphere supported Pt catalyst was successfully prepared through a one-pot process. The modification of carbon sphere was operated in liquid phase reaction without any post-processing, and Pt was directly reduced to deposit on the composite support in the same suspension system. The role of Mn as a modifier can show change of adsorption state by XPS, XRD and electrochemical tests. At the same time, the improved the methanol electrooxidation performance, can be proved from lower adsorptive capacity and lower electrooxidation peak potential.
