The utilization of clean and unlimited hydrogen energy is an attractive avenue to tackle the crises of energy and environmental pollution, and exploring high-active, earth-abundant and stable electro-catalysts for the oxygen evolution reaction (OER) is critical to the practicability for electrochemical water splitting. Herein, a nanohybrid with Fe-doped CoSe2 nanoparticles embedded in N-doped bamboo-like carbon nanotubes (denoted as FCS@N-CT) is prepared through simple pyrolysis followed by the selenization employing easily available raw materials for the first time. The received FCS@N-CT shows excellent electrocatalytic comprehensive properties for OER in 1M KOH solution, comparable to and even surpassing the fresh RuO2. Specifically, it requires an overpotential of only 330 mV to deliver a current density of 10 mAcm(-2), and achieves higher current density than that of RuO2 with elevating the potential over 1.652 V vs. reversible hydrogen electrode. More strikingly, FCS@N-CT exhibits a smaller Tafel slope and much better durability than those of RuO2. The remarkable electrocatalytic performance of FCS@N-CT can be ascribed to the unique nanostructure featuring abundant active sites, the favorable conductive network for rapid charge transfer, the synergistic effect between FCS and N-CT, along with the protection of FCS by carbon layers for strong robustness under catalytic conditions.
