Example Embodiment
[0018] Example 1:
[0019] The first step, preparation of bismuth nitrate solution and ammonium metavanadate solution
[0020] Take the quantity of nitric acid: ethanol: bismuth nitrate=1:28:0.2, and ultrasonicate for 30 minutes to obtain the bismuth nitrate solution. Measure nitric acid: ethanol: ammonium metavanadate=1:28:0.05 parts by mass, ultrasonic for 10min to obtain ammonium metavanadate solution.
[0021] The second step, preparation of bismuth vanadate and silica aerogel microsphere composite
[0022] The ammonium metavanadate solution was slowly added dropwise to the bismuth nitrate solution to obtain a mixed solution of ammonium metavanadate and bismuth nitrate, wherein the mass ratio of ammonium metavanadate and bismuth nitrate was 1:4. First put the silica aerogel microspheres in a container to vacuum, and then slowly drop the mixed solution of ammonium metavanadate and bismuth nitrate into the container, where the silica aerogel microspheres and bismuth nitrate are in ...

[0034] Example 3:
[0035] The first step, preparation of bismuth nitrate solution and ammonium metavanadate solution
[0036] Take the quantity of nitric acid: ethanol: bismuth nitrate=1:15:0.5, and ultrasonicate for 30 minutes to obtain the bismuth nitrate solution. Measure nitric acid: ethanol: ammonium metavanadate=1:15:0.125 parts by mass, ultrasonic for 10min to obtain ammonium metavanadate solution.
[0037] The second step, preparation of bismuth vanadate and silica aerogel microsphere composite
[0038] The ammonium metavanadate solution was slowly added dropwise to the bismuth nitrate solution to obtain a mixed solution of ammonium metavanadate and bismuth nitrate, wherein the mass ratio of ammonium metavanadate and bismuth nitrate was 1:4. First put the silica aerogel microspheres in a container to vacuum, and then slowly drop the mixed solution of ammonium metavanadate and bismuth nitrate into the container, where the silica aerogel microspheres and bismuth nitrate are in...
