Dual electric fields coupled with hollow porous structures synergistically enable efficient electrocatalytic nitrate-to-ammonia conversion
A new model A/R-TiO<sub>2</sub>/CuO<sub><i>x</i></sub> electrocatalyst for upcycling nitrate to ammonia is constructed by coupling dual electric fields and hollow porous structures, which can enhance the local concentrations of NO<sub>3</sub><sup>-</sup> and intermediates, and can lower the energy barrier of *NO to *NOH. Therefore, high NH<sub>3</sub> yield (0.292 mmol h<sup>-1</sup> cm<sup>-2</sup>) and Faradaic efficiency (92.31%) at -1.4 V <i>vs.</i> SCE are achieved.
