Manganese (II) oxide (MnO) nanoparticles with nitrogen-doped (N-doped) carbon coating were fabricated via an efficient carbonization process using pyrrole, acrylonitrile and pyridine as different carbon sources, respectively. High-resolution transmission electron microscopy (HR-TEM) characterizations reveal the uniform carbon coating on the MnO nanoparticles. X-ray photoelectron spectroscopy (XPS)...
Pt-Mn3O4 catalysts with carbon black as conductive agent and support show a remarkable activity for oxygen evolution reaction because of a synergistic effect between Pt and Mn3O4. The Pt-Mn3O4/C catalyst with a weight ratio of Pt to Mn3O4 of 3:1 gives the best performance. After loading with Mn3O4, the binding energy value of Pt 4f and Mn 2p respectively has a positive and negative shift, which will...
