Construction of C/MoS2 nanocomposite for highly efficient electrocatalytic NRR

Electrochemical N2 reduction reaction (NRR) has been considered as a promising and green process to replace conventional Haber−Bosch process. However, the presence of sluggish reaction kinetics and competitive hydrogen evolution reaction (HER) can result in poor activity and unsatisfactory selectivity. Here, we proposed C/MoS2 catalysts by a facile ‘one-pot’ hydrothermal method. Benefiting from porous nanosphere structure, it shows outstanding charge transfer rate, which accelerates NRR kinetics. As a result, C/MoS2 exhibited a conspicuously improved NRR performance with a high Faradaic efficiency (FE) of 8.2% at −0.7 V. In addition, this electrocatalyst showed marvelous stability.
