Structure-activity relationships of Fe/N-doped carbon catalysts for electrochemical hydrodechlorination

Figure 4. (A and B) CV curves of Fe/NC-10 in 0.1 M Na2SO4 electrolyte (A) with and without CHCl3, (B) with different ending potentials; (C) EPR spectra of Fe/NC-10 in 0.1 M Na2SO4 electrolyte with and without CHCl3 at -0.8 V vs. RHE; (D) CH4 yield rate and FE of Fe/NC-10 with the addition of TBA; (E) DEMS results for the EHDC of CHCl3 over Fe/NC-10. Error bars in (D) represent the standard deviation of three independent replicate experiments. Data plotting and fitting were performed using Origin 2022. CV: Cyclic voltammetry; EPR: electron paramagnetic resonance; RHE: reversible hydrogen electrode; FE: Faradaic efficiency; TBA: tert-butanol; DEMS: differential electrochemical mass spectrometry; EHDC: electrochemical hydrodechlorination.
