摘要: A catalytic material which includes a metal oxide catalyst anchored to a nano-sized metal oxide crystal as support and functions well at low temperatures. The catalytic material may optionally include another metal oxide as a promoter deposited on the surface of the support to modify the properties of the metal oxide catalyst and/or the properties of the support. The catalyst may be vanadium oxide, tungsten oxide, manganese oxide, chromium oxide or molybdenum oxide; the support may be TiO2, SiO2, Al2O3, ZrO2, or WO3; and the promoter may be vanadium oxide, tungsten oxide, manganese oxide, chromium oxide or molybdenum oxide. The present invention also provides a method of producing the catalytic materials, which is useful in removing ammonia and other nitrogen containing contaminants.
