Embodiment 1
[0024] The invention discloses a preparation method of highly active photocatalytic particles. The highly active photocatalytic particles are coated on the surface of nanometer titanium monoxide by n-butyl titanate. It is converted into titanium dioxide by hydrolysis to form polytitanium photocatalytic particles with titanium monoxide as the core and titanium dioxide as the coating.
[0025] The method comprises the steps of:
[0026] Step 1, adding titanium monoxide to a ball mill, adding a small amount of distilled water to stir to form a slurry, and ball milling for 2 hours, then using hot nitrogen to seal and blow dry, and obtain nano-titanium monoxide after cooling;
[0027] Step 2, slowly adding nano-titanium monoxide to n-butyl titanate for low-temperature microwave reaction for 2 hours, stirring to form a suspension slurry;
[0028] Step 3, spray the suspension slurry and distilled water simultaneously in a constant temperature reaction kettle for constant temperature...
