The general proposed mechanism for this reaction initiated with the O2 evolution from H2O with releasing 4H+ and 4e. The released protons finally are consumed in the cathode to afford H2 by consuming the electrons received through the external circuit from the anode (Fig. 1) [39]. The ...
Equimolar quantities (43 mmol) of zirconium tetrachloride and 1,4-benzenedicarboxylic acid were reacted in the presence of a large excess (684 mmol) of benzoic acid in a DMF:H2O (1650:83 mL) solvent. The resulting product was washed sequentially with DMF and MeOH before being dried under ...
