Cr3C2 Nanoparticle-Embedded Carbon Nanofiber for Artificial Synthesis of NH3 through N2 Fixation under Ambient Conditions
Source abstract
Abstract
Industrial production of NH3 heavily depends on the conventional Haber–Bosch process under rigorous conditions with a large amount of energy consumption and carbon emissions. Electrocatalysis exhibits an intriguing prospect for the N2 reduction reaction (NRR) at ambient conditions. In this case, a high-efficiency and low-cost catalyst is paramount. In this letter, Cr3C2 nanoparticles and carbon nanofiber composite (Cr3C2@CNF) are proposed as a noble-metal-free NRR electrocatalyst for converting N2 to NH3 with an excellent selectivity. The optimal Faradic efficiency and NH3 yield rate achieved are as high as 8.6% and 23.9 μg h–1 mgcat.–1 at −0.3 V vs reversible hydrogen electrode in 0.1 M HCl, respectively. Theoretical calculations show a low reaction barrier of merely 0.53 eV in the enzymatic route for this catalyst.
