Cu doping enhances electroreduction of nitrate to ammonia over NbS <sub>2</sub> hierarchical nanosheets
In this work, we developed a three-dimensional nanosheet-like Cu doped NbS<sub>2</sub> structure (Cu-NbS<sub>2</sub>) that not only facilitates the exposure of more active sites on both the edges and basal planes but also increases the solid-liquid contact area. Moreover, the distinct difference in adsorption energy between the Cu sites and NO<sub>3</sub><sup>-</sup> reactants enhances the interaction between Cu and NO<sub>3</sub><sup>-</sup>. Consequently, the Cu-NbS<sub>2</sub> catalyst achieves a maximum faradaic efficiency of 91.2% and an impressive NH<sub>3</sub> yield rate of 230.9 µmol h<sup>-1</sup> mg<sup>-1</sup>. This study provides a promising strategy for efficient nitrate remediation and environmentally friendly NH<sub>3</sub> synthesis.
