Embodiment 1
[0030] Put the weighed bismuth nitrate and aluminum nitrate (molar ratio = 1:5) into a beaker, add 1 mL of nitric acid with a concentration of 1 mol / L to dissolve them, and then add 0.5 mL of distilled water to make the solution volume 1.5 mL. ; Add 2.42g of ZSM-5 powder according to the proportion, form equal volume immersion after ultrasonication, and let it stand for 24 hours to make the solution and powder immersed evenly. Put the powder after standing for 24 hours in a drying oven at 80°C to dry, transfer the powder to a crucible after drying, and put it into a muffle furnace for calcination at 450°C for 2 hours. After calcination is completed, the concentration of the bismuth-containing compound is: 0.2mol% bismuth-doped powder. Finally, the prepared powder was loaded into the graphite mold, and then put into the SPS equipment for sintering. The SPS preparation process was carried out under the condition of high-purity argon. The heating rate was 90°C / min; the sinterin...
Embodiment 2
[0032]Put the weighed bismuth chloride and aluminum chloride (molar ratio = 1:3) into a beaker, add 2mL of hydrochloric acid with a concentration of 2mol / L to dissolve them, and then add 1mL of distilled water to make the solution volume reach 3mL ; Add 3.63g of ZSM-11 powder according to the proportion, form an equal volume of impregnation after ultrasonication, and let it stand for 24 hours to make the solution and powder impregnate evenly. Put the powder after standing for 24 hours in a 90°C drying oven to dry, transfer the powder to a crucible after drying, and put it in a muffle furnace for calcination at 550°C for 1 hour to obtain a bismuth-containing compound with a concentration of 1mol%. Bismuth powder. Finally, put the prepared powder into the graphite mold and put it into the SPS equipment for sintering. The SPS preparation process is carried out under the condition of high-purity argon. The heating rate is 80°C / min; the sintering temperature is 1250°C; the holdin...

[0034] Put the weighed bismuth oxide and aluminum hydroxide (molar ratio = 1:6) into a beaker, add 2mL of nitric acid with a concentration of 1mol / L to dissolve them, and then add 1mL of distilled water to make the solution volume reach 3mL; Add 4.84g of ZSM-5 powder according to the ratio, form equal-volume impregnation after ultrasonication, and let it stand for 24 hours to make the solution and powder impregnate evenly. Put the powder after standing for 24 hours in an 80°C drying oven to dry, transfer the powder to a crucible after drying, put it in a muffle furnace for calcination at 450°C and keep it for 2 hours to obtain a bismuth-containing compound with a concentration of 0.5mol%. bismuth-doped powder. Finally, put the prepared powder into the graphite mold and put it into the SPS equipment for sintering. The SPS preparation process is carried out under the condition of high-purity argon. The heating rate is 100°C / min; the sintering temperature is 1300°C; the holding...
