摘要	Platinum(Pt)is the state-of-the-art electrocatalyst towards hydrogen evolution reaction(HER), but its atom-utilization efficiency and durability need to be further improved. In this work, we prepared the highly dispersed Pt atoms supported on defects-rich Ru nanoparticles substrate (Ru NPs@Pt) by substrate-enhanced electroless deposition method. The results of single electron paramagnetic resonance confirm the existence of the defects on Ru NPs substrate and the X-ray diffraction combined with transmission electron microscopy reveals the highly dispersed Pt atoms. Exchange current density of HER on the Ru NPs@Pt is up to 2.39 mA/cm2, which is significantly higher than that of commercial Pt/C, demonstrating the boosted HER intrinsic activity. Mass activity is as high as 32.34 A/mgPt that is 9.37 times higher than that of Pt/C at an overpotential of 50 mV. Significantly, the Ru NPs@Pt delivers the greatly enhanced durability in comparison with the Pt/C one even under the ultralow Pt loading(2 µg/cm2), indicating that the defects-rich Ru NPs substrate could improve the electrocatalytic activity and durability of Pt simultaneously. © 2024 Science Press.
