Embodiment l
[0019] 1) Dissolve 10 g of tetraethyl orthosilicate and 0.5 g of Tween-80 in 5 mL of ethanol to form a solution, and then slowly add it into 30 mL of Stir in deionized water for 2 hours at room temperature, then transfer the mixture to an autoclave, crystallize at 120°C for 72 hours, cool to room temperature, filter, wash with deionized water for 3 times, and place the solid in a vacuum dryer at 60°C After drying for 12 hours, it was calcined in a muffle furnace at 550°C for 3 hours to obtain copper (II) ion-modified mesoporous silica microspheres.
[0020] 2) After mixing 20 g copper(II) ion-modified mesoporous silica microspheres with 0.001 g ammonium molybdate, 1 g phthalic anhydride, 1 g ammonium chloride, and 3 g urea, place In a reaction kettle containing 70 mL of xylene, reflux reaction at 130°C for 2 hours under slow stirring conditions, after cooling to room temperature, suction filtration, washing with deionized water until the filtrate was neutral, and vacuum drying...
