Recycling urine for bioelectrochemical hydrogen production using a MoS₂ nano carbon coated electrode in a microbial electrolysis cell.

ABSTRACT: In this study, a novel molybdenum disulfide (MoS₂) nano-carbon (NC) coated cathode was developed for hydrogen production in a microbial electrolysis cell (MEC), while treating simulated urine with 2-6 times dilution (conductivity <20 mS cm^-1). MoS₂ nanoparticles were electrodeposited on the NC coated cathodes at -100, -150 and -200 μA cm^-2 and their performances were evaluated in the MEC. The chronopotentiometry (CP) tests showed the improved catalytic activity of MoS₂-NC cathodes with much lower cathode overpotential than non-MoS₂ coated electrodes. The MoS₂-NC200 cathode, electrodeposited at -200 μA cm^-2, showed the maximum hydrogen production rate of 0.152 ± 0.002 m³ H₂ m^-2
