Embodiment 1

[0014] Example 1, preparing scandium nitrate, silica sol, and sodium aluminate with a mass ratio of 1:3:1. Manganese sulfate 10g, silica sol 30g, sodium aluminate 10g, tetraethylammonium bromide (TEABr) 10ml, 5ml 2 mol / L sodium hydroxide, 200ml deionized water.

[0015] Step 1. First, 10g of silica sol and 10g of sodium aluminate were ultrasonically shaken in an oil bath at 100°C for 3 hours to remove impurities;

[0016] Step 2. Put 10ml of tetraethylammonium bromide (TEABr), 10g of scandium nitrate, and 5ml of 2 mol / L sodium hydroxide solution in an ultrasonic oscillating water bath at 100°C for 2h to remove impurities;

[0017] Step 3. Add the silica sol dropwise into the flask, then add dropwise 100ml of ionized water and sodium hydroxide solution at a rate of 20 drops per minute, and at the same time heat the oil bath at 100°C for 3h with magnetic stirring;

[0018] Step 4. Add sodium aluminate to the above solution, then add the template agent tetraethylammonium bromide...

Embodiment 2

[0024] The preparation method is the same as that of Example 1, except that the mass ratio of scandium nitrate, silica sol, and sodium aluminate is 1:1:1. Manganese sulfate 10g, silica sol 10g, sodium aluminate 10g.

Embodiment 3

[0026] The preparation method is the same as that of Example 1, except that the mass ratio of scandium nitrate, silica sol, and sodium aluminate is 1:1:2. Manganese sulfate 10g, silica sol 10g, sodium aluminate 20g.
