The invention discloses a preparation method of a porphyrin functionalized titanium dioxide-montmorillonite nanocomposite, comprising the steps of: adding butyl titanate to anhydrous ethanol, stirring to obtain a transparent solution I; and slowly drying the transparent solution I Adding to the nitric acid solution to obtain the solution II; adding the montmorillonite to the deionized water to prepare the montmorillonite suspension III; slowly adding the solution II to the montmorillonite suspension III, stirring to obtain a white solution IV; The solution IV is quickly poured into the reaction vessel and placed in a microwave hydrothermal reaction kettle; after the reaction is completed, it is naturally cooled to room temperature, then filtered, centrifuged, and dried to obtain product A; product A is dispersed in deionized water, and then The mixture is reacted with a tetracarboxyphenylporphyrin solution, and after completion of the reaction, it is centrifuged, washed, and dried to obtain a final product. The nanocomposite prepared by the process of the invention increases the catalytic efficiency on the one hand and broadens the photoresponse range on the other hand. |
