Facile synthesis of Ni based metal-organic frameworks wrapped MnO2 nanowires with high performance toward electrochemical oxygen evolution reaction

The synthesis of high-performance electrochemical oxygen evolution catalyst Ni/DMTD/MnO2 and its application in oxygen evolution reaction in alkaline solution. The potential at 10 mA cm-2 was 1.492 V (vs RHE) in 1 M KOH aqueous solution. The results indicated that MnO2 has the capability to enhance not only the catalytic activity but also operation stability of Ni/DMTD/MnO2 towards oxygen evolution reaction.110
