Hydrogen sulfide (H 2 S) is an extremely hazardous chemical waste that is generated at large scale in many industries; its abatement has long been an energy‐extensive and cost‐ineffective liability due to the thermodynamic limitations of the selected approaches and low value of the final products, sulfur and water. Here we introduce an attractive method for H 2 S abatement that yields value‐added products via a thermodynamically favorable process. Specifically, sodium naphthalenide (Na‐NAP) is used to capture H 2 S to produce anhydrous Na 2 S nanocrystals and 1,4‐dihydronaphthalene, which are important materials for batteries and liquid fuels, respectively. This multipurpose process is driven by the acid/base neutralization reaction between hydrogen cations from H 2 S and radical anions from naphthalenide. It is spontaneous and irreversible at ambient temperature and pressure, proceeding to completion very rapidly.
