Plasma assisted dissociation of hydrogen sulfide

► Hydrogen sulfide dissociation studied in four plasma discharges. ► The study covers corona, dielectric barrier, streamer, and glow discharges. ► Results compared using specific energy requirement (SER). ► High E/n discharges (corona, DBD, streamer) have SER of 12-14 eV/molec. ► SER of contracted glow discharge at low E/n and higher temperature is 2.4 eV/molec.
