Synergistic Effect of Fe Doping and Plasmonic Au Nanoparticles on W₁₈O₄₉ Nanorods for Enhancing Photoelectrochemical Nitrogen Reduction.

ABSTRACT: Photoelectrochemical (PEC) nitrogen fixation has opened up new possibilities for the production of ammonia from water and air under mild conditions, but this process is confronted by the inherent challenges associated with theoretical and experimental works, limiting the efficiency of the nitrogen reduction reaction. Herein, we report for the first time a novel and efficient photoelectrocatalytic system, which has been prepared by assembling plasmonic Au nanoparticles with Fe-doped W₁₈O₄₉ nanorods (denoted as WOF-Au). (i) The introduction of exotic Fe atoms into nonstoichiometric W₁₈O₄₉ can eliminate bulk defects of the W₁₈O₄₉ host, which resulted in narrowing bandgap energy and facilitating electron-hole separation and tran
