Abstract—The catalytic activity of transition metal complexes supported on VION chemisorptive filament was
studied in the process of the low-temperature oxidation of hydrogen sulfide under the flow conditions. Manga-
nese-, copper-, and nickel-containing catalysts are shown to be most efficient. The activity of these catalysts per
one atom of supported metal remains constant independently of the presence of functional groups that are not
bound to metal. Sulfide complexes of transition metals exhibit catalytic activity. The only reaction product is
elementary sulfur.
