摘要： 本研究通过共沉淀法结合硒化策略合成了普鲁士蓝类似物（PBA）衍生过渡金属硒化物（FeSe2、CoSe2和FeSe2/CoSe2）碳基复合材料，并系统评估了三种催化剂在碱性电解液中作为析氢反应（HER）阴极的催化活性和稳定性。采用XRD、SEM和XPS对合成的催化剂进行物相分析和形貌表征。结果表明，FeSe2/CoSe2材料表现出最优异的电催化析氢性能，在10 mA cm?2下的过电位仅为118 mV，Tafel斜率仅为86 mV dec?1，催化性能优于单一相的FeSe2和CoSe2。FeSe2/CoSe2性能增强主要归因于FeSe2和CoSe2界面间的强电子耦合作用优化了其电子结构。此外，FeSe2/CoSe2催化剂在经过8 h的稳定性测试后，CP始终保持在91.74%。且三种催化剂经过1000次CV循环后的LSV曲线几乎不变，表现出良好的电化学稳定性。

Abstract: Using a coprecipitation method combined with a selenization strategy, we synthesized Prussian blue analogue (PBA) derived transition metal selenides-based (FeSe2, CoSe2, and FeSe2/CoSe2) composites and systematically evaluated the catalytic activity and stability of these three catalysts as cathodes for the hydrogen evolution reaction (HER) in alkaline electrolytes. The characterization of the synthesized catalysts were performed by using XRD, SEM, and XPS to determine it phase composition, morphology, and surface chemistry. The results indicate that the FeSe2/CoSe2 composite exhibits the most outstanding electrocatalytic hydrogen evolution performance, with an overpotential of only 118 mV at 10 mA cm?2 and a Tafel slope of only 86 mV dec?1. FeSe2/CoSe2 catalytic performance surpasses that of the single-phase FeSe2 and CoSe2, owing to the strong electronic coupling at the FeSe2/CoSe2 interface, which optimizes the electronic structure of FeSe2/CoSe2. After an 8 h CP test, the FeSe2/CoSe2 catalyst exhibited an overpotential retention rate of 91.74%, and the LSV curves of all three catalysts remained nearly unchanged after 1,000 CV cycles.
