Embodiment 1
[0018] (1) 99.9% analytically pure chemical raw material SrCO 3 , CoO and TiO 2 , press Sr 2 co 4 Ti 15 o 36 Chemical formula weighing ingredients.
[0019] (2) Mix the raw materials prepared in step (1), put them into a ball mill jar, add zirconia balls and absolute ethanol, ball mill for 8 hours, mix and grind until fine, take it out and dry it, and pass through a 200-mesh sieve.
[0020] (3) Pre-fire the uniformly mixed powder in step (2) at 980°C, keep it warm for 6 hours, cool it down to room temperature naturally, and then use a ball mill to make the particle diameter smaller than 2 μm, that is, to obtain Sr 2 co 4 Ti 15 o 36 powder.
[0021] The prepared photocatalyst can remove 97.6% of methyl orange in 120 minutes under the irradiation of visible light with a wavelength greater than 420nm.
