摘要
Through inverted-design rather than modifying the generally-assumed S active sites in popular MoS_(2),we unlock the potential of Mo sites and successfully prepared novel MoS_(2)@Ni_(3)S_(2)/NF core-shell nanospheres as a catalyst for the high-performance hydrogen evolution reaction(HER).TheΔGH at the Mo site is optimized via Ni_(3)S_(2)to achieve excellent HER activity.At low current densities,it has similar activity to the Pt/C.However,its performance is better than Pt/C at high density.Moreover,our catalyst shows a considerable stability at a variety of current densities for 50 h,promising to substitute noble metal catalysts in application of commercial alkaline electrocatalysts.
