Title: Method for oxidizing hydrogen sulfide to elemental sulfur

Abstract: A method for selectively oxidizing hydrogen sulfide to elemental sulfur is disclosed. The elemental sulfur can be effectively recovered from a gas mixture containing hydrogen sulfide in the presence of a multi-component catalyst. The multi-component catalyst includes an antimony-containing substance and a vanadium-and-magnesium-containing material. The antimony containing substance may be antimonous oxide (Sb.sub.2 O.sub.3) or antimony tetraoxide (.alpha.-Sb.sub.2 O.sub.4), and the vanadium and magnesium containing material may be magnesium pyrovanadate (Mg.sub.3 V.sub.2 O.sub.8) or Mg.sub.2 V.sub.2 O.sub.7.
