dc.description.abstract | Although the electrochemical reaction is an effective and great promise to produce hydrogen, the realization of efficient and stable catalysts is still a significant challenge in the various electrochemical systems, such as water splitting and Zn-CO2 system. Herein, we report Ru nanoparticles anchored at edge-selectively nitrogenated graphitic nanoplatelets (Ru-ENG) instead of on the basal plane in two-dimensional (2D) graphitic substrate. The Ru nanoparticles interacted with both of armchair-ENG and zigzag-ENG substrate lead to favorable hydrogen evolution activities of icosahedron cluster Ru-13 in Ru-ENG at a universal pH, compared to Ru metal cluster. The spontaneous electron re-construction between edge-site of N and ruthenium particles in Ru-ENG catalyst is attributed to the faster reaction kinetics with lower Tafel slopes and higher turnover frequencies than the benchmark Pt/C catalyst in any pH conditions. More importantly, the Ru-ENG electrocatalyst exhibited superior long-term consecutive stability (over 1,500 h) at a high current density of 100 mA cm(-2) in the practical water-splitting system. | - |
