本文采用溶剂热法制备了不同钴/钼摩尔比（6% - 12%）的钴掺杂二硫化钼（Co - MoS₂），并将其负载在氮掺杂碳纤维/碳纸（NCFCP）上（Co - MoS₂/NCFCP），作为一种高效的析氢反应（HER）电催化剂。NCFCP基底是通过在碳纸上电化学沉积聚吡咯，然后进行热处理制备的。所获得的9% Co - MoS₂/NCFCP复合催化剂表现出优异的电催化析氢活性，在10 mA/cm²的电流密度下过电位低至174 mV，塔菲尔斜率小至52 mV/dec，并且具有长期稳定性。因此，Co - MoS₂/NCFCP复合材料作为一种高效且地球上储量丰富的析氢电催化剂材料具有很大的潜力。（C）2020爱思唯尔有限公司。版权所有。
In this paper, Co-doped MoS2 (Co-MoS2) with various Co/Mo mole ratio (6%-12%) decorated on nitrogen-doped carbon fiber/carbon paper (NCFCP) (Co-MoS2/NCFCP) is fabricated by a solvothermal method as an efficient electrocatalyst for hydrogen evolution reaction (HER). The NCFCP substrate is prepared by electrochemical deposition of polypyrrole on carbon paper followed by heat treatment. The obtained 9% Co-MoS2/NCFCP hybrid catalyst exhibits an excellent electrocatalytic HER activity with a low overpotential of 174 mV at 10 mA cm(-2), a small Tafel slope of 52 mV dec(-1) and long-term stability. Thus, Co-MoS2/NCFCP hybrid holds high potential as an efficient earth-abundant electrocatalyst material for HER. (C) 2020 Elsevier B.V. All rights reserved.
