MoO2@C nanoparticles decorated on reduced graphene oxide for electrocatalytic nitrite reduction to ammonia

Abstract

Electrocatalytic nitrite (NO2) reduction is a promising and eco-friendly method for ammonia (NH3) production. Here, carbon-coated MoO2 nanoparticles decorated on reduced graphene oxide (MoO2@C/RGO) are reported to be an effective electrocatalyst for NO2 reduction to NH3. The outer carbon shell not only effectively enhances the stability of the electrocatalyst but also promotes the charge transfer during the NO2 reduction process, thereby significantly improving the catalytic performance. In neutral media, MoO2@C/RGO provides a high NH3 yield of 17.64 ± 0.10 mg h−1 cm−2 and a high FE of 95.79% ± 0.50% at −0.9 V. Furthermore, a Zn–NO2 battery with MoO2@C/RGO exhibits a peak power density of 2.125 mW cm−2 and an open circuit voltage of 1.33 V.
