Abstract It is important to develop highly efficient and durable electrocatalysts for overall water splitting in industry application. Herein, we synthesized a novel 1D pea-like nitrogen-doped bimetallic carbide (N-Co6Mo6C) nanorods. Benefiting from the synergistic effect of N doping and good conductivity of the thin amorphous carbon shell on the surface of N-Co6Mo6C, the N-Co6Mo6C shows remarkable activity for both hydrogen evolution reaction (HER) in acid and alkaline solution and oxygen evolution reaction (OER) in alkaline solution, respectively. Furthermore, using the N-Co6Mo6C as both the anode and the cathode for overall water splitting, a cell voltage of only 1.58 V is needed to derive a current density of 10 mA/cm2. This work offers a new insight for the design of the non-noble bimetallic carbide with excellent electrocatalytic performance for overall water splitting.

N掺杂的Co6Mo6C纳米棒作为高活性和耐用的双功能电催化剂用于水分解

摘要 在工业应用中开发高效、耐用的电催化剂用于整体水分解具有重要意义。在此，我们合成了一种新型的一维豌豆状氮掺杂双金属碳化物（N-Co6Mo6C）纳米棒。受益于 N 掺杂的协同作用和 N-Co6Mo6C 表面薄无定形碳壳的良好导电性，N-Co6Mo6C 在酸碱溶液中的析氢反应（HER）和析氧反应中均表现出显着的活性。 OER) 分别在碱性溶液中。此外，使用 N-Co6Mo6C 作为阳极和阴极进行整体水分解，仅需 1.58 V 的电池电压即可获得 10 mA/cm2 的电流密度。
