2D MXene-derived Nb2O5/C/Nb2C/g-C3N4 heterojunctions for efficient nitrogen photofixation

Novel 2D MXene-derived Nb₂O₅/C/Nb₂C/g-C₃N₄ showed a high nitrogen reduction rate in water (0.365 mmol h⁻¹ g_cat⁻¹); the nitrogen reduction efficiency could be further promoted 2.5 times (0.927 mmol h⁻¹ g_cat⁻¹) with the optimized pH of 9.
