However, the commercial viability of this process is hindered by the inability of the electrocatalyst to achieve higher current densities for UOR due to the competition with the OER. In this study, a cobalt-MOF-derived CoPBO/Co-MOF composite electrocatalyst was synthesized over Ni foam using a solvothermal method followed by a simple chemical reduction method for UOR. The CoPBO/Co-MOF@NF demonstrated excellent electrocatalytic bifunctional activity with low potentials of +1.32 V and ?0.095 V for UOR and HER, respectively, at 100 mA/cm2 in 1 M KOH +0.33 M urea solution. Under industrial-level alkaline conditions (6 M KOH), the potential requirement for UOR is further decreased to 1.14 V, also achieving a high current density of 1 A/cm2 at only 1.35 V, which is below the thermoneutral voltage for water splitting. Comprehensive electrochemical kinetic analysis revealed that the CoPBO/Co-MOF composite effectively combines the attributes of CoPBO, for strong OH? adsorption and CoOOH formation, with the affinity of Co-MOF for urea adsorption and CO2 desorption, leading to enhanced UOR performance. Furthermore, in a zero-gap electrolyzer configuration, the CoPBO/Co-MOF@NF catalyst demonstrated remarkable efficiency in actual cow urine (with 1 M KOH), requiring only 1.39 V to achieve a current density of 100 mA/cm2 which is 0.5 V lower than in urea-free water splitting. 2025 Subject The topic of the resource Co-MOF; Composite catalyst; Green hydrogen; Urea oxidation Publisher An entity responsible for making the resource available Elsevier Ltd Relation A related resource ISSN: 3603199; CODEN: IJHED Language A language of the resource English Type The nature or genre of the resource Article Rights Information about rights held in and over the resource Restricted Access; Hardcopy may be available in the library Format The file format, physical medium, or dimensions of the resource online
