Embodiment 1
[0016] Example 1 Prepare a sample with a mass ratio of bismuth nitrate pentahydrate, silver nitrate, and cerium nitrate in a ratio of 18:3:1. Bismuth nitrate pentahydrate 18g, silver nitrate 3g, cerium nitrate 1g, DEG 50ml, KCl 3g, deionized water 200ml, ascorbic acid 1g, glyceryl tristearate 0.5g, acetic acid 20ml, methyltrimethoxysilane coupling agent 2ml.
[0017] Step 1. Purging 18g of bismuth nitrate pentahydrate in a nitrogen atmosphere for 2h, then dissolving it in 50ml of DEG solution, heating and stirring in a water bath at 60°C for 2h to obtain solution A;
[0018] Step 2. Dissolve 3g of KCl in 100ml of deionized water, and then treat it with infrared for 2 hours to obtain solution B;
[0019] Step 3, then the prepared solution B is added dropwise to solution A at a rate of 60 drops per minute to obtain a white precipitate;
[0020] Step 4, and then subject the obtained white precipitate to thermal alkali treatment: now purging under hot air at 80°C for 2 hours, the...
