In this study, a novel molybdenum disulfide (MoS(2)) 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 600 mg L(−1) NH(3)-N) can adversely affect the biofilm architecture and the bacterial activity at the anode of the MEC. Exoelectrogenic bacteria for this system at the anode were identified as Tissierella (Clostridia) and Bacteroidetes taxa. Maximum ammonia-nitrogen (NH(3)-N) and phosphorus (PO(4)(3−)-P) removal were 68.7 and 98.6%, respectively. This study showed that the newly fabricated MoS(2)-NC cathode can be a cost-effective alternative to the Pt cathode for renewable bioelectrochemical hydrogen production from urine.
