Synchronous generation of green oxidants H2O2 and O3 by using a heterojunction bifunctional ZnO/ZnS@C electrocatalyst

ZnO/ZnS@C-750 achieved 90% selectivity for H 2 O 2 and 11% Faraday efficiency for gaseous O 3 . H 2 O 2 and O 3 are simultaneously generated in the electrolyzer and they utilize the synergistic effect to degrade organic pollutants efficiently.
