Nitrate(NO3-)electroreduction reaction(NO3-RR)provides an attractive and sustainable route for NO3-pollution mitigation or energy-saved ammonia(NH3)synthesis.In this work,high-quality B and Fe co-doped Co2P hollow nanocubes(B/Fe-Co2P HNCs)are successfully synthesized though simultaneous boronation-phosphorization treatment,which reveal outstanding selectivity,activity,stability for the NO3-to NH3 conversion in neutral electrolyte because of big surface area,fast mass transport,super-hydrophilic surface,and optimized electronic structure.B/Fe-Co2P HNCs can achieve the high NH3 yield rate(22.67 mg h-1 mgcat-1)as well as Faradaic efficiency(97.54％)for NO3-RR,greatly outperforming most of non-precious metal based NO3-RR electrocatalysts.
