Producing "green urea" using renewable energy, N2, and CO2 is a long-considered challenge. Herein, an electrocatalyst, Bi2S3/N-reduced graphene oxide (RGO), was synthesized by loading the Bi2S3 nanorods onto N-RGO via hydrothermal method. The Bi2S3/N-RGO composites exhibit highest yield of urea (4.4 mmol g–1 h–1), which 12.6 3.1 times higher than that (0.35 h–1) (1.4 respectively. N-RGO, because its porous open-layer structure, improves mass transfer efficiency stability, while basic groups (-OH -NH2) promote adsorption activation CO2. promotes absorption inert N2. Finally, defect sites synergistic effect on work simultaneously to form from N2 This study provides new insights into synthesis under ambient conditions strategy for design development material green synthesis.
