摘要	Electrocatalytic reduction of N-2 to ammonia (NH3) at ambient conditions has attracted widespread attention, and revealing the mechanism has been a remarkably challenging problem for decades. This work developed a low-cost and efficient multiple heteroatom codoped porous carbon catalyst from municipal sludge (MSB-P), which demonstrated excellent electrochemical stability and selectivity for the electrochemical N-2 reduction reaction (N2RR). In 0.1 mol/L HCl solution, a high NH3 yield rate of 35.76 mu g.h(-1).mg(-1) cat. and an excellent Faraday Efficiency (FE) of 7.79% at-0.7 V vs. RHE (reversible hydrogen electrode) were obtained under ambient conditions. Furthermore, the electrocatalytic mechanism of MSB-P for N2RR was also revealed by in situ Fourier transform infrared spectroscopy (FTIR) data, and an associative route was identified. These findings provide an exciting new method for fabricating inexpensive and efficient carbon-based catalysts for production of NH3 at ambient conditions. (C)& nbsp;2022 Elsevier Ltd.
