ABSTRACT:
The present invention provides a catalyst used in wastewater treatment process wherein not only an organic compound not containing nitrogen, sulfur or halogen is decomposed, but also a nitrogen-containing compound, a sulfur-containing compound and an organic halogeno compound are effectively decomposed, thereby wastewater are treated with excellent efficiency for a long period of time. The invention also provides a production process for the catalyst and said wastewater treatment process. The first catalyst comprises: an oxide of iron as an A component; and at least one kind of element as a B component selected from a group consisting of cobalt, nickel, cerium, silver, gold, platinum, palladium, rhodium, ruthenium and iridium. The second catalyst comprises: an oxide as an A component containing iron and at least one kind of element selected from a group consisting of titanium, silicon and zirconium; and at least one kind of element as a B component selected from a group consisting of cobalt, nickel, cerium, silver, gold, platinum, palladium, rhodium, ruthenium and iridium.
