Examples
Embodiment 1
[0036] (1) Add 8ml of distilled water to 50ml of isopropanol and stir evenly in a water bath at 65°C.
[0037] (2) Add 1 ml of concentrated ammonia water and 1 ml of 1-3 aryl ether dendritic phthalocyanine complex (M is zinc) stock solution (0.02 mol / L) to the mixed solution, and continue stirring for 5 min.
[0038] (3) Add 8 mL of tetraethyl orthosilicate to the solution, continue to stir for 12 h to make it fully hydrolyzed, and finally filter the solution and wash (10 mL each time for 3 times with isopropanol, 10 mL each time for 5 times with distilled water) mL), and the solid was dried at 70 °C to obtain the desired catalyst.
