Multichannel nitrogen-doped carbon fiber confined Fe3C nanoparticles for efficient electroreduction of nitrate

Abstract

A novel 1D hierarchical architecture with dispersed Fe3C nanoparticles confined in multichannel nitrogen-doped carbon fibers (Fe3C/MNCFs) is reported as efficient NO3RR electrocatalyst. The Fe3C/MNCFs-800 demonstrates the nitrate conversion of 90.9%, N2 selectivity of 99.53%, for up to 15 cycles.
