摘要

For the first time, highly-dispersed ruthenium precursors via a hydrogen-bond-driven melamine-cyanuric acid supramolecular complex (denoted CAM) self-assembly-assisted synthesis of uniform ruthenium nanoparticles with superior HER performance under both acidic and alkaline conditions are reported. Electrochemical tests reveal that when the current density is -10 mA cm(-2), the optimal Ru/CNO electrocatalyst could express low overpotentials of -18 mV and -46 mV, low Tafel slopes of 46 mV dec(-1) and 100 mV dec(-1), in 0.5 M H2SO4 and 1.0 M KOH, respectively. The remarkable HER performance could be attributed to uniform ruthenium with the aid of highly dispersed ruthenium precursors (Ru-CAM) and subsequent annealing results in uniform ruthenium nanoparticles.
