摘要:Rational design of surface plasmon-enhanced electrocatalysts can effectively integrate solar energy into fuel cells. Herein, iron and nitrogen codoped carbon (Fe/NC) nanoparticles synthesized with microemulsion are used to absorb and photo-reduce Ag ions in solutions to form Ag nanoparticles on Fe/NC (Ag-Fe/NC). Different Ag-Fe/NC materials are prepared by adjusting the concentration of AgNO3 solution. Among them, Ag-Fe/NC obtained with 0.5 mg ml(-1) AgNO3 solution shows the highest oxygen reduction reaction (ORR) catalytic performance and light-enhanced ORR characteristics, even better than commercial Pt/C. Besides, Ag-Fe/NC displays excellent long-term stability and high methanol resistance for ORR performances in alkaline medium. Therefore, this study will provide a new method for integrating light to recover Ag ions in solutions and improve electrocatalytic properties.
