Embodiment 1
[0035] Prepare 0.02mol / L of H 2 PtCl 6 solution, pour 80 mL of deionized water into a beaker, and then add anatase TiO 2 20g, turn on magnetic stirring, set the speed to 500r / min, stir for 20min, and then add H 2 PtCl 6 Solution 5.13mL, Co(NO 3 ) 6H 2 O 6.98g, continue to stir for 3h; transfer the beaker to a spray dryer and dry at 120°C for 7h; grind the dried powder and place it in a muffle furnace, at a heating rate of 5°C / min in air The temperature was raised from room temperature to 500 °C under the atmosphere, and the powder was calcined for 3 hours. The powder obtained after calcination was the treated NH 3 escape catalyst.
Embodiment 2
[0037] Prepare 0.02mol / L of H 2 PtCl 6 solution, pour 80 mL of deionized water into a beaker, and then add CeO 2 20g, turn on magnetic stirring, set the speed to 500r / min, stir for 20min, and then add H 2 PtCl 6 Solution 5.13mL, Co(NO 3 ) 6H 2O 6.98g, continue to stir for 3h; transfer the beaker to a spray dryer and dry at 120°C for 5h; grind the dried powder and place it in a muffle furnace, at a heating rate of 5°C / min in air The temperature was raised from room temperature to 500 °C under the atmosphere, and calcined for 3 hours. The powder after calcination was treated with NH 3 escape catalyst.
Embodiment 3
[0039] Prepare 0.02mol / L of H 2 PtCl 6 solution, pour 80 mL of deionized water into a beaker, and then add Al 2 O 3 20g, turn on magnetic stirring, set the speed to 500r / min, stir for 20min, and then add H 2 PtCl 6 Solution 5.13mL, Co(NO 3 ) 6H 2 O 6.98g, continue to stir for 3h; transfer the beaker to a spray dryer and dry at 120°C for 6h; grind the dried powder and place it in a muffle furnace, at a heating rate of 5°C / min in the air The temperature was raised from room temperature to 500 °C under the atmosphere, and calcined for 3 hours. The powder after calcination was treated with NH 3 escape catalyst.
