Abstract

We report defective Cu-rich CuFe₂O₄ nanofibers as an efficient catalyst for reducing nitrate, which achieves an NH₃ yield of 9.21 mg h⁻¹ mg_cat.⁻¹ and a Faradaic efficiency of 91.08% in 0.1 M PBS and 0.1 M NO₃⁻ and exhibits excellent stability. The reaction mechanism is revealed by theoretical calculations.
