Selenium vacancy-rich and heteroatom-doped CoSe/Mo2CTx MXene prepared using ionic liquid dopants for pH-universal hydrogen evolution and flexible supercapacitors
文献摘要：
Vacancy engineering is a useful methodology in the development of catalysts and electrode materials.Herein,we report the introduction of Se-vacancy pairs in heteroatom-doped(N,B,and F)CoSe/Mo2CTx MXene(NBF-CoSe/Mo2CTx)to enhance the hydrogen evolution reaction(HER)and supercapacitor activ-ities via an ionic liquid-mediated method.Se vacancy pairs and heteroatom doping enable the realloca-tion of local electron states and add active sites,improving the electrochemical activity of NBF-CoSe/Mo2CTx with high HER activities over a broad range of pH.At a current density of 10 mA cm-2,over-voltages of 70 and 81 mV are respectively produced in 0.5 M H2SO4 and 1 M KOH.The optimal structure also exhibits outstanding electrochemical performance in an asymmetric supercapacitor with an energy density of 34.2 Wh kg-1 at a power density of 15989.6 W kg-1.This study opens new avenues for the introduction of Se vacancies and heteroatom doping to improve the application performance.
