In range of 300℃～900℃, all the transition metal oxide catalysts could get high ammonia conversion, during the initial stages of the reaction, the SO〓 conversion is relatively low since the catalysts have not been sulfureted, but it increases gradually and attain constant with rising temperature and time continuance,〓 is better than other catalysts in reactivity and elemental sulfur selectivity; XRD indicates that, in the SO〓-SCR process, stable transition metal sulfide is generated which is very important to SO〓 reduction and transition metal sulfide probably is the active phase of catalyst, further the reduction of SO〓 by H〓 to H〓S is the limiting step of all process, then the activity is somewhat related to its lattice oxygen yet not so notable; XPS indicates that little sulfur on surface exists as S〓 in sulfate, showing that TiO〓 could restrain the generation of sulfate.
