Figure 13. (A) In-situ FTIR spectra for Fe-Co_0.85Se/FeCo LDH in different constant potentials (1.1-1.7 V vs. RHE); (B) Under 1.45 V vs. RHE, the In-situ time-resolved FTIR measurements of Fe-Co_0.85Se/FeCo LDH; (C) Diagram of possible intermediates in the critical steps for UOR; (D) Hydrogen adsorption on FeCo LDH, Fe-Co_0.85Se, and Fe-Co_0.85Se/FeCo LDH; (E) The diagram of free energy for UOR on FeCo LDH, Fe-Co_0.85Se, and Fe-Co_0.85Se/FeCo LDH^[126]. LDH: Layered double hydroxide; RHE: reversible hydrogen electrode; UOR: urea oxidation reaction.
