摘要 | The electrochemical nitrogen reduction reaction (ENRR), as a promising green N(2)fixation strategy for the production of ammonia under ambient conditions, has attracted significant attention. Herein, we report the synthesis of copper nanocrystals anchored on a carbonized corn gel (Cu NCs/CCG) for electrochemical N(2)fixation to NH3, in which the rich O-containing functional groups on CCG are beneficial for efficiently dispersing and stabilizing the copper nanocrystals. As a result, the obtained Cu NCs/CCG achieve a high faradaic efficiency (FE) of 25.89% and a large NH(3)yield rate of 1514 mu g h(-1)mg(Cu)(-1)at -0.3 Vversusan RHE in 0.1 M Na2SO4. Moreover, the Cu NCs/CCG demonstrate good ENRR stability and durability. This work paves the way for developing high-performance ENRR electrocatalysts utilizing biomass derivatives as precursors for NH(3)synthesis. |
