摘要/Abstract

摘要： In view of recent environmental concerns, electrochemical water splitting for hydrogen (H₂) as one of the important reactions has getting more and more attention in these years. Herein, we synthesized a series of Mo, N, and P co-doped carbons as efficient electrocatalysts to replace the expensive platinum-based catalysts. As the final products, the combination of Mo₂C nanoparticles (NPs) and N, P co-doped carbons were fabricated using a simple molten salt process. More notably, KCl as the template could be recycled and reused via water washing. The ratios of the precursors could affect the structure of the final production, and therefore further determine the performance of electrocatalytic towards hydrogen evolution reaction (HER). Owing to extensive supplies of active sites and heterogeneous structures that provide transfer channels for electrons, the optimal sample of GUPMo-2.00KCl exhibited the best HER activity among the as-synthesized samples, including low overpotentials, small Tafel slope, and good stability. This work opens up a novel prospect for the designing of high-performance electrocatalysts.
