AB  - Developing more active and stable electrode materials for oxygen evolution 
      reaction (OER) and urea oxidation reaction (UOR) is necessary for 
      electrocatalytic water and urea oxidation which can be used to generate hydrogen. 
      Here, a low-cost vanadium-doped mesoporous cobalt oxide on Ni foam (V/meso-Co/NF) 
      electrodes are obtained via the grouping of an in-situ citric acid (CA)-assisted 
      evaporation-induced self-assembly (EISA) method and electrophoretic deposition 
      process, and work as highly efficient and long-lasting electrocatalytic materials 
      for OER/UOR. In particular, V/meso-Co/NF electrodes require 329 mV overpotential 
      to maintain a 50 mA/cm(2), with exceptional long-term durability of 30 h. 
      Interestingly, V/meso-Co/NF also exhibits excellent electrocatalytic UOR 
      performance, reaching 50 and 100 mA/cm(2) versus RHE at low potentials of 1.34 
      and 1.35 V, respectively. By employing the V/meso-Co/NF materials as both the 
      anode and cathode, this urea electrolysis assembly V/meso-Co/NF-5 (+,-) reaches 
      current densities of 100 mA cm(-2) at 1.62 V in KOH/urea, which is nearly 340 mV 
      lesser than classical water electrolysis. The V/meso-Co/NF-5 electrocatalysts 
      also exhibit remarkable durability for electrocatalytic OERs and UORs. The 
      obtained findings revealed that the synthesized V/meso-Co/NF might be a promising 
      electrode materials for overall urea-rich wastewater management and H(2) 
      generation from wastewater.
