Embodiment 1
[0022] Example 1.Fe 9 Ti 1 o xPreparation of -400 Composite Oxide Nanocatalyst
[0023] Accurately weigh 14.54g ferric nitrate and 0.96g titanium sulfate and dissolve in 100mL H 2 Fully stir in O, and then use ammonia water as a precipitating agent, slowly drop into the mixed solution of the iron-titanium precursor under the condition of stirring, and control the final pH of the solution to be 10. After suction filtration and washing, dry in an oven at 110°C for 12 hours, grind evenly, and then roast at 400°C for 4 hours in an air atmosphere in a muffle furnace to obtain Fe 9 Ti 1 o x -400 Catalyst. its NH 3 -SCR activity results, XRD, H 2 -TPR and NH 3 -TPD see attached Figure 1-4 .
Embodiment 2
[0024] Example 2.Fe 9 Ti 1 o x Preparation of -600 Composite Oxide Nanocatalyst
[0025] Accurately weigh 14.54g ferric nitrate and 0.96g titanium sulfate and dissolve in 100mL H 2 Fully stir in O, and then use ammonia water as a precipitating agent, slowly drop into the mixed solution of the iron-titanium precursor under the condition of stirring, and control the final pH of the solution to be 10. After suction filtration and washing, dry in an oven at 110°C for 12 hours, grind evenly, and then roast at 600°C for 4 hours in an air atmosphere in a muffle furnace to obtain Fe 9 Ti 1 o x -600 catalyst. its NH 3 -SCR activity results and XRD characterization results are attached Figure 1-2 .
