SUMMARY The decomposition of hydrogen sulfide (H 2 S) to hydrogen and sulfur with Al 2 O 3 , MoO x /Al 2 O 3 , CoO x /Al 2 O 3 and NiO/Al 2 O 3 packed non‐thermal plasma dielectric barrier discharge reactor was studied. The reaction was carried out with 5‐mm discharge gap during the decomposition of 5 vol.% H 2 S at 150 ml/min (STP) flow rate. Typical results indicated the conversion of ~50% at a specific input energy of ~0.92 kJ/l H 2 S and 10% (in length) packed reactor showed the best conversion. Among the catalysts studied, MoO x and CoO x supported on Al 2 O 3 showed high performance, which may be caused by synergy between plasma excitation of the carrier gas molecules and catalytic behaviour of MoO x and CoO x .
