外文摘要：Rational design and production of materials for highly effective and environmental-friendly electrocatalytic hydrogen evolution reaction(HER)play a pivotal role in advancing renewable energy utilization.Structural engineering of noble metal nanomaterials can significantly boost catalytic performance through atomic rear-rangement,electronic structure modification and surface reactivity modulation.Here,RuNi alloy is synthesized using a novel high temperature liquid shock method(HTLS)with instant Joule heating treatment at 1073 K under the mixed atmosphere of Argon(Ar)and CO.The synthesis process involves an aqueous solution containing metal precursors,capping agents,reductant agents and carbon black.Particularly,the as-prepared RuNi-HTS nano-structures with hexagonal close-packed(hcp)phase demonstrate impressive electrocatalytic HER activity in alkaline conditions,requiring only 28 mV of overpotentials at a current density of 10 mA cm-2.Note that the Tafel slope is 159.2 mV dec-1.Furthermore,this versatile HTLS method can be extended to synthesize other catalysts,including Ru-HTS,PtRu,and PtZn,all of which show commendable performance for HER as well.This study lays the groundwork for the strategic design and high-throughput synthesis of novel materials with fine-tuned structure and refined size,enabling highly efficient and environmental-friendly electrocatalysis.
