N-doped graphene anchored ultrasmall Ir nanoparticles as bifunctional electrocatalyst for overall water splitting
文献摘要：
Seeking for extremely active and durable bifunctional electrocatalysts towards the overall water splitting possesses a strategic significance on the development of sustainable and clean energy for the replacement of fossil fuels.Ir-based nanomaterials are deemed as one of the most high-efficiency oxygen evolution reaction electrocatalysts while the hydrogen evolution reaction performance is unfavorable.In this work,we report a one-pot hydrothermal synthesis of N-doped graphene anchored Ir nanoparticles(Ir/N-rGO)with ultrasmall particle size(～2.0 nm).Apart from the predictably superior OER performance,the resultant Ir/N-rGO also displays excellent hydrogen evolution reaction(HER)performance,requiring merely 76 and 260 mV overpotentials to achieve the current density of 10 mA cm-2 towards HER and OER,respectively.When applied as the bifunctional electrodes for overall water splitting,Ir/N-rGO needs a lower overpotential(1.74 V)to achieve a current density of 50 mA cm-2 in alkaline solution,exceeding that of Pt/C and RuO2 couple(1.85 V).Thus,the as-fabricated Ir/N-rGO has a commendable prospect in the practical application of alkaline water electrocatalysis.
