Cu(II) porphyrin-Mediated Reed-Straw-Carbon-Based Cu-N-C Catalysts for Efficient Electrocatalytic Nitrate Reductions

Аннотация

Herein, the Cu^IIporphyrin-mediated reed-straw-carbon-based Cu-N-C catalyst was prepared through high-temperature thermal treatment, and the structures were characterized by SEM, XRD, Raman, FT-IR and XPS. During the electrocatalytic experiments, the Cu-N-C catalyst exhibits excellent nitrate reduction performance (56.33%) and high energy utilization efficiency (63.16%) at E = -1.3V. Also, the electrocatalytic stability and ion influence in the simulated waste water were also investigated. These results provide an opportunity to further explore the efficient electrochemical removal of nitride from M-N-C catalysts.
