(A) FT-IR spectra of pyridine-2,5-dicarboxylic acid (H2PDC), ZrCl4 and Zr-UiO-66-PDC. (B) Powder X-ray diffraction (PXRD) pattern of electrosynthesized Zr-UiO-66-PDC. (C) Large- and close-view FE-SEM images of Zr-UiO-66-PDC by constant current electrolysis at I = 30 mA cm−2 and t = 1800s. (D) N2 adsorption/desorption isotherm. BET and BJH of Zr-UiO-66-PDC by the constant current electrolysis at I = 30 mA cm−2 and t = 1800s. (E) Energy-dispersive X-ray spectroscopy (EDX) and elemental mapping analysis of electrosynthesized Zr-UiO-66-PDC. The structures of the compounds were drawn using ChemOffice 12.0 (CambridgeSoft).
