| 英文摘要 | The development of Pt-free catalysts for the alkaline hydrogen evolution reaction (HER), which is widely used in industrial scale water-alkali electrolyzers, remains a contemporary and pressing challenge. Ruthenium (Ru) has excellent water-dissociation abilities and could be an alternative water splitting catalyst. However, its large hydrogen binding energy limits HER activity. Here, a new approach is proposed to boost the HER activity of Ru through uniform loading of Ru nanoparticles on triazine-ring (C3N3)-doped carbon (triNC). The composite (Ru/triNC) exhibits outstanding HER activity with an ultralow overpotential of approximate to 2 mV at 10 mA cm(-2); thereby making it the best performing electrocatalyst hitherto reported for alkaline HER. The calculated metal mass activity of Ru/triNC is >10 and 15 times higher than that of Pt/C and Pt/triNC. Both theoretical and experimental studies reveal that the triazine-ring is a good match for Ru to weaken the hydrogen binding on Ru through interfacial charge transfer via increased contact electrification. Therefore, Ru/triNC can provide the optimal hydrogen adsorption free energy (approaching zero), while maintaining the strong water-dissociation activity. This study provides a new avenue for designing highly efficient and stable electrocatalysts for water splitting. |
