Copper catalysis for enhancement of cobalt leaching and acid utilization efficiency in microbial fuel cells

•Species of Cu(II) improved cobalt leaching and acid utilization efficiencies in MFCs.•A pH of 2.0 was more preferable than 3.0 for Cu(II)-catalyzed cobalt leaching in MFCs.•A solid/liquid ratio of 100–200mg/L was matched with a Cu(II) dosage of 10mg/L.•The estimated Ea for Cu(II)-catalyzed cobalt l...
