摘要：NOVELTY - The present invention relates to a preparation method of titanium dioxide visible photocatalyst in which the carbon and nitrogen are doped. Said method includes the following steps: firstly, adding nitrogen source into the microemulsion formed from n-butyl titanate, inorganic acid, Triton X-100, n-hexyl alcohol and cyclohexane and making mole ratio value of nitrogen and titanium be 0.5-4, then placing the nitrogen-contained microemulsion in a reactor, making hydrothermal reaction for 13 hr at 120deg.C, finally washing the product obtained after hydrothermal reaction, separating and drying so as to obtain the invented target product.
