Catalytic oxidation of H₂S at room temperature has been regarded as a promising method for removing malodorous H₂S pollution. However, most of the existing research has primarily focused on developing catalysts with high sulfur capacity, i.e., high elemental sulfur selectivity, which was unfavored for the catalyst regeneration. The present work prioritizes efficient water wash regeneration as a key objective. A series of activated carbon fibers (ACFs) was synthesized using a synergistic strategy of "nitrogen doping-plasma defect engineering". The certain amount of nitrogen species ensured a certain level of sulfur capacity. The plasma defect engineering can result in the enhancement of surface acidity and defect density, which worked together to make the catalyst with high sulfate selectivity. The O₂-plasma modified NH₃-ACF-O10 catalyst achieved the best catalytic performance with appropriate sulfur capacity (0.21 g/g) and highest sulfate selectivity (85.40%). Importantly, it can be easily regenerated by water wash, and almost 83.33% sulfur capacity can be recovered. Besides, superoxide radicals (O₂^•-) were identified as the primary reactive oxygen species for the reaction. And the reaction obeyed a Langmuir-Hinshelwood (L-H) like mechanism, i.e., the reaction was proceeded via chemisorbed H₂S and O₂^•-, which was adsorbed and activated by defect.
