In/Al2O3 catalyst was prepared with impregnation method and coprecipitation method, respectively,and research on selective reduction of NOx with the catalyst was carried out. The results show that the catalyst prepared by coprecipitation has higher low-temperature activity and NO selectivity. The bimetal component catalyst of In-Ti/Al2O3 was obtained by the carrier modification with transition metal Ti. And In-Ti/Al2O3 has high activity due to amorphous In oxides and high specific surface area. The added TiO2 can weaken the interaction between In and Al2O3 to form amorphous InTiO2 crystal, resulting in low- er reduction temperature of In.
