Abstract:The N-modified TiO2 samples were synthesized by the solid-phase reaction of Formamide and Tetrabutyl titanate with template of P123. The photocatalysts were characterized by X-ray powder diffraction (XRD), N2 adsorption-desorption (BET), Photoluminescence(PL). N-TiO2 had a mesoporous structure, increasing the pore size, increasing the surface area to 111.767m2/g, reducing the recombination of electron and hole on the anatase N-TiO2.The photo-catalytic activity was tested through photo-degrading the sodium humate. Degradation ratio of sodium humate could reach up to 98% after 120mins, when amount of P123 was 5%, catalyst amount was 10g/L and initial concentration was 5mg/L. And the photocatalytic degradation reaction of sodium humate followed pseudo-first-order Langmuir -Hinshelwood kinetics equation.
