Preparation method for reproducible low-temperature selective catalytic reduction denitration catalyst

The invention relates to a preparation method for a reproducible low-temperature selective catalytic reduction denitration catalyst. The preparation method comprises the following steps: S1) preparing a supporting material; S2) adding 57ml butoxy acetic titanium into a 500ml beaker, stirring and then heating to 50 DEG C; S3) adding 50ml 1mol/L HNO3; S4) adding 160ml vinyl triethoxy silane, keeping at 50 DEG C, and stirring for 24 hours for sufficient hydrolysis reaction, wherein the mole ratio of Ti to Si is 3:1; S5) centrifugally separating at the speed of 6000 rpm, and washing for 5 times with deionized water; S6) drying for 12 hours in an oven at 110 DEG C; S7) calcining for 4 hours in a muffle furnace at 500 DEG C and grinding, thereby acquiring a porous TiO2-SiO2 double oxide supporting material; and S8) loading Fe-Mn-W oxides. According to the preparation method provided by the invention, the reproducible low-temperature selective catalytic reduction denitration catalyst can be acquired and can be regen
