摘要

MoSe2@HCNF hybrids are synthesized via a facile hydrothermal method. The as-synthesized MoSe2@HCNF hybrids are used as the cathode catalyst of Li-O-2 batteries for the first time. The successful growth of MoSe2 nanosheets on the surface of HCNF mitigates the agglomeration of MoSe2 nanosheets and results in more edge sites exposed. And the electronic conductivity of the hybrids is enhanced by the combination of HCNF. Therefore, the MoSe2@HCNF hybrids exhibit superior catalytic activity, especially the OER catalytic activity for the charge process. The charge over-potential of the Li-O-2 batteries is greatly reduced, delivering a charge voltage platform of similar to 3.69 V at 0.1 mA cm(-2), and the cycle performance is improved. According to this study, it can be expected that metal selenides have a great potential to be used as the cathode catalyst for Li-O-2 batteries.
