In order to broaden the temperature window of nitrogen oxide removal efficiency of selective catalytic reduction （SCR） catalyst, the research of Ti-Ce-W mixed oxide catalysts was conducted. Among a series of Ti-Ce-W mixed oxide catalysts prepared by SHS (self-propagating high-temperature synthesis) method, catalyst with n(W)∶n(Ti)=0.2(n is the amount of substance) showed a 100% NO removal efficiency from 200 to 440 ℃ and 100% N2 selectivity below 400 ℃. The SCR characteristic of TiC0.2W0.2Ox was also tested under high GHSV( gas hourly space velocity) of 11 400 h-1. Besides by directly deposit the catalyst on cordierite carrier, a 95% NO removal efficiency and a 100% N2 selectivity from 250 to  450 ℃ were obtained.
