Hydrogen Peroxide Electrosynthesis From Seawater

ABSTRACT Hydrogen peroxide (H2O2) electrosynthesis via a two‐electron oxygen reduction reaction (2e– ORR) from seawater holds a promising perspective for the marine economy. However, the competitive 4e– ORR pathway and high concentration of Cl– in seawater pose great challenges. Recently, Zhang et al. developed high‐performance electrocatalysts based on NiPS3 nanosheets for efficient H2O2 production from seawater. The seawater electrolysis system based on NiPS3 enables large‐scale production of H2O2, which can be applied to wastewater degradation, biomass valorization, and agricultural fields. This finding facilitates the sustainable conversion of seawater into high‐value products.
