Embodiment 1
[0020] Example 1. Preparation of CeTi support
[0021] Dissolve 0.81g of cerium nitrate and 9.12g of titanium sulfate in 350mL of distilled water, stir magnetically at room temperature for 30min to mix evenly, then add concentrated ammonia water drop by drop, the concentration of concentrated ammonia water is 13.2mol L -1 , adjust the pH to 10, at 90 o Magnetic stirring in C water bath for 3h to make the precipitation complete, aging for 24h, suction filtration, washing, filter cake at 120 o C dried for 12h, ground evenly, in the air atmosphere in the muffle furnace at 550 o C is calcined for 6 hours to obtain a cerium-titanium solid solution carrier, which is marked as CeTi.
Embodiment 21Z
[0022] Example 2. 1ZrO 2 / Preparation of CeTi catalyst
[0023] Mix 1 g of CeTi carrier with ultrapure water, stir for 30 min, add 0.82 mL of 0.1 mol L -1 Zirconium nitrate solution, continue to stir for 30min, at 90 o Stir and evaporate to dryness in a C oil bath; put the sample at 120 o C drying 12h, grinding, 500 under air atmosphere in a tube furnace o C is roasted for 6h to get 1ZrO 2 / CeTi catalyst. Its XRD measurement result sees figure 1 , H 2 -TPR assay results see figure 2 , the denitrification performance test results are shown in image 3 .
