Abstract
The high cost and over-potential loss of the cathode are primary bottlenecks of the microbial electrolysis cell (MEC) technology for efficient \H2\ production from renewable biomass. In this study, novel NiFe layered double hydroxide (NiFe LDH) electrocatalyst was directly grown on nickel foam for \H2\ evolution from actual brewery wastewater and its fermentation effluent. The new cathode demonstrated comparable high \H2\ rate (2.01
