摘要：It is challenging to synchronously introduce Ru nanoparticles with strong H* adsorption ability and Ru dopants with excellent electronic regulation to improve hydrogen evolution reaction (HER) performance. With these in mind, this work creatively adopts the capture&ions exchange strategy to construct the Ru@HMCS/Ru-CoP catalyst with the Ru nanoparticles-coated hollow mesoporous carbon spheres (HMCS) shell and the Ru-doped CoP core. Notably, Ru nanoparticles and Ru dopants synergistically promote the optimization of HER kinetics. Moreover, the unique core-shell structure effectively increases the active area, conductivity, and structural stability of Ru@HMCS/Ru-CoP. As expected, the eta 10 value of Ru@HMCS/Ru-CoP catalyst (2.9 mV) is 48.8 mV lower than that of Pt/C (51.7 mV). In summary, this work greatly improves the utilization of noble metal atoms and points out the direction for the development of electrocatalysts with low-load noble metal content.
