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.
