摘要	Although microbial fuel cells (MFCs) is considered as one of the most promising technology for renewable energy harvesting, low power output still accounts one of the bottlenecks and limits its further development. In this work, it is found that Cu2+ (0.1 mu g L-1-0.1 mg L-1) or Cd2+ (0.1 mu g L-1-1 mg L-1) significantly improve the electricity generation in MFCs. The maximum power output achieved with trace level of Cu2+ (similar to 6 nM) or Cd2+ (similar to 5 nM) is 1.3 times and 1.6 times higher than that of the control, respectively. Further analysis verifies that addition of Cu2+ or Cd-2+ effectively improves riboflavin production and bacteria attachment on the electrode, which enhances bacterial extracellular electron transfer (EET) in MFCs. These results unveil the mechanism for power output enhancement by Cu2+ or Cd2+ addition, and suggest that metal ion addition should be a promising strategy to enhance EET as well as power generation of MFCs.
