Fabricating of the dual-sited Cu doped Co3O4 on Nickel Foam (Cu-Co3O4/NF) for segmentally efficient electrochemical nitrate reduction under low conductivity

To tackle the removal of low-concentration nitrate contamination, this work utilizes electrocatalytic reduction technology to convert nitrate into recoverable ammonia, using as-prepared Cu doped Co 3 O 4 on nickel foam composites as the cathode.
