The invention discloses a wide-temperature denitration catalyst and a preparation method thereof. The catalyst uses an antimony doped titanium dioxide nanorod array as a carrier, uses vanadium pentoxide as an active ingredient and uses molybdenum oxide and cerium oxide as auxiliary agents. The titanium dioxide nanorod array is directly grown on a base plate by a hydrothermal method; the combiningforce of titanium dioxide and the base plate is enhanced, so that the catalyst has high abrasive resistant intensity and long service life; through the ordered arrangement of the titanium dioxide nanorod array, the specific surface area can be improved; the active sites are increased; the catalyst activity is improved; titanium dioxide is subjected to antimony doping, so that the sulfur poisoningresisting performance of the catalyst can be enhanced. Cerium oxide and molybdenum oxide are loaded on the carrier, so that low-temperature activity of the catalyst can be improved; the reaction temperature is expanded; the catalyst has high denitration efficiency, high stability and high selectivity in a temperature range of 150 to 420 DEG C. The catalyst can be widely applied to various industrial furnace SCR denitration systems.
