文摘
- •
A hybrid air-cathode with the optimal carbon black/graphite ratio of 1:5 is made.
- •
The maximum H2O2 yield is 11.9 mg L−1 h−1 cm−2.
- •
Continuous flow without H2O2 accumulation increases current efficiency.
- •
Oxygen for H2O2 synthesis is mainly contributed by air diffusion (66–94%).
- •
The use of bioanode increases H2O2 yield and current efficiency.
