Preparation method of photocatalytic material for vehicle air purification

The invention discloses a preparation method of a photocatalytic material for vehicle air purification. The preparation method comprises: 1, adding zinc acetate to absolute ethanol, stirring uniformlyuntil completely dissolving, adding sodium lauryl sulfate, ultrasonically dispersing, and carrying out stirring cooling to obtain a zinc alcohol solution; 2, adding phenyltrichlorosilane to a toluenesolution, stirring until completely dissolving, slowly adding the zinc alcohol solution in a dropwise manner, and stirring to form a suspension liquid; 3, adding small-pore vesuvianite to the suspension liquid, carrying out a constant temperature ultrasonic reaction for 2-5 h, carrying out a microwave reaction for 1-2 h, cooling, slowly adding distilled water in a dropwise manner, and carrying out constant temperature stirring for 2-4 h to obtain a pre-plated vesuvianite solution; and 4, placing the pre-plated vesuvianite solution in a pressure reducing distillation reaction, carrying out gradient pressure reducing di
