Abstract

Abstract : In this work, hydrophobic carbon-doped tin disulfide (C-SnS2 ) was fabricated for the first time and adopted as an advanced catalyst for the eNRR. Abstract : As a new method of ammonia (NH3 ) synthesis, the electrocatalytic nitrogen reduction reaction (eNRR) has generated widespread attention. The tin-based catalysts represent a broad development prospect in the field of electrocatalysis, but their eNRR performances need to be improved. In this work, hydrophobic carbon-doped tin disulfide (C-SnS2 ) was fabricated for the first time and adopted as an advanced catalyst for the eNRR. The doped C may adsorb more N2 and significantly improve the conductivity, which will contribute synergistically to the performance of the eNRR. The C-SnS2 nanoflower catalyst achieved a satisfactory NH3 yield rate (62.3 μg h −1 mg −1 cat. ) and high Faraday efficiency (23.06%) at −0.2 V vs. RHE in acidic conditions (0.1 M HCl). This work may provide new methods for the further development of high activity eNRR catalysis.
