An efficient electrocatalytic in-situ hydrogen peroxide generation for ballast water treatment with oxygen groups.

The in-situ electrochemical production of hydrogen peroxide (HO) offers a promising approach for ballast water treatment. However, further advancements are required to develop electrocatalysts capable of achieving efficient HO generation in seawater environments. Herein, we synthesized two-dimensional lamellated porous carbon nanosheets enriched with oxygen functional groups, which exhibited exceptional performance in HO electrosynthesis.
