Facile Synthesis of MOF-derived Mn3O4@N-doped Carbon with Efficient Oxygen Reduction

Integration of MnO(x)into the carbon matrix proves a viable strategy to improve the electrochemical performance of MnO(x)materials. Mn(3)O(4)nanoparticle-decorated N-doped carbon composites (Mn3O4@N-doped carbon) were facilely prepared from a non-porous eight-fold interpenetrated Zn-II-based MOF, which involves first synthesis of bimetallic Mn/Zn-MOF in one-pot reaction followed by direct pyrolysis at 1000 degrees C. In 0.1mKOH solution, the optimal Mn3O4@N-doped carbon exhibits decent oxygen reduction activity with the onset potential (E-onset) of 0.94 V (vs. RHE) and half-wave potential (E-1/2) of 0.81 V (vs. RHE), excellent methanol tolerance as well as good durability.
