Biomass Juncus derived carbon decorated with cobalt nanoparticles enables high-efficiency ammonia electrosynthesis by nitrite reduction

Abstract

Highly dispersed Co nanoparticles on biomass Juncus derived carbon achieve superb nitrite reduction performances with a faradaic efficiency of 96.9% and an NH 3 yield of 2.8 mol h −1 g Co −1 . The catalytic mechanism is revealed by DFT calculations.
