The rational construction and design of a new type of high-efficiency hydrogen evolution reaction(HER)electrocatalyst under alkaline conditions is a key challenge to achieve economic and sustainable hydrogen production.Ru@CNT(CNT=carbon nanotube)nanocluster materials were successfully synthesized by a simple,rapid and solvent-free microwave method.In alkaline media,the nanoclusters exhibit excellent hydrogen evolution catalytic activity.Among them,the overpotential of Ru@CNT(90 s)was 16 mV(10 mA·cm-2)and the Tafel slope was 25.5 mV·dec-1.A TOF value of 13.5 s-1 was achieved at an overpotential of 100 mV,which is one of the best performance catalysts among the noble metal-based electrocatalysts reported so far.
