Wastewater is one of the most common by-products almost every industrial process. Treatment wastewater alone, before disposal, necessitates an excess energy. Environmental concerns over use fossil fuels as a source energy have prompted surge in demand for alternative sources and development sophisticated procedures to extract from unconventional sources. municipal alone accounts about 3% global electricity while amount embedded waste at least 2–4 times greater than required treat same effluent. The microbial electrolysis cell (MEC) efficient technologies waste-to-product conversion that uses electrochemically active bacteria convert organic matter into hydrogen or variety without polluting environment. This paper highlights existing obstacles future potential integration Microbial Electrolysis Cell with other processes like anaerobic digestion coupled system, membrane bioreactor thermoelectric micro converter.

Hydrogen production by electrocatalytic water splitting is an efficient and economical technology, however, severely impeded the kinetic-sluggish low value-added anodic oxygen evolution reaction. Here we report nickel-molybdenum-nitride nanoplates loaded on carbon fiber cloth (Ni-Mo-N/CFC), for concurrent electrolytic productions of high-purity hydrogen at cathode formate anode in low-cost alkaline glycerol solutions. Especially, when equipped with Ni-Mo-N/CFC both cathode, established electrolyzer requires as 1.36 V cell voltage to achieve 10 mA cm-2, which 260 mV lower than that aqueous solution. Moreover, high Faraday efficiencies 99.7% H2 95.0% have been obtained. Based excellent electrochemical performances Ni-Mo-N/CFC, from solutions are energy-efficient promising technology renewable clean energy supply future.
