“…31–35 Sulfides, as a toxic, malodorous and corrosive compound, are abundantly distributed in waste gas and wastewater of petrochemical and industrial production, causing a series of environmental pollution problems. 36–39 A promising sulfion rich wastewater treatment method is upcycling by converting S 2− to value-added S using the electrochemical sulfion oxidation reaction (SOR). 40–42 Furthermore, the SOR ( E 0 = −0.48 V vs. SHE) is driven relative to the OER at an ultra-low theoretical potential.…”

Sulfide oxidation reaction (SOR) is a semi‐reaction for the electrochemical decomposition of hydrogen sulfide. Combining SOR with the hydrogen evolution reaction (HER) allows for the simultaneous splitting of hydrogen sulfide (H2S) to produce green hydrogen, reducing energy input and environmental pollution. However, the phenomenon of sulfur passivation on the anode leads to catalyst deactivation, posing a bottleneck in developing efficient SOR. Electrocatalysts with decent performance and sulfur‐tolerance play a central role in the application of SOR. Here, recent progress on electrocatalysis mechanisms and catalyst design strategies of SOR are summarized. A summary of recent progress is made in materials such as alloys, metal oxides, metal sulfides, metal selenides, and heterostructures as SOR catalysts. Additionally, some valuable design and modulation strategies are highlighted and included. Finally, this review offers an outlook on the future directions in this emerging field.
